▼ This study investigates the factors that support or obstruct the use of steel grade S460 in the Dutch building industry. The research was limited to European hot-rolled sections and focused on buildings which have primarily a non-residential function. In order to identify these factors, a qualitative (exploratory) research study has been carried out. On the basis of an extensive literature review a semi-structured interview schedule was constructed to guide the interview process. Data was collected in a focus group interview with stock holders and during fourteen in-depth interviews with structural engineers, steel fabricators, contractors and a steel producer. Interviews were conducted face to face, and then transcribed. The results are invaluable in gaining an in-depth understanding of the perceptions held by stakeholders in the Dutch building industry, and which factors influence these perceptions.

▼ Pressure locked gratings have many uses, both on land and at sea. This is mainly due to the high degree of flexibility in dimensions and load bearing capacity. Despite the many uses in our surroundings, the term pressure locked grating is unknown to many. This term refers to the way in which the most important connection in pressure locked gratings is manufactured. Pressure locked gratings are galvanized and/or coated to prevent corrosion, galvanization is almost always used. This thesis is primarily focused on the behavior of galvanized pressure locked gratings. A pressure locked grating is made up of three type of bars: load bearing bars, cross bars and support bars. The connections between the load bearing bars and the cross bars are realized by pressing the cross bar into premade notch in the load bearing bar. The bars will deform plastically, which results in a connection based only on friction. This connection is called a pressure locked connection. The load bearing bars serve primarily for load transfer in one direction. The pressure locked connection weakens the load bearing bars. The cross bars redistribute a local load over the load bearing bars outside of the loading area and reduce the buckling length of the individual load bearing bar. The support bars are spot-welded to both the load bearing and cross bars. Pressure locked gratings are calculated according to RAL-GZ-638, a standard published by the Deutsches Institut fü
r Gütesicherung und Kennzeichnung e.V. In this standard, pressure locked gratings are calculated on the basis of linear elasticity theory. A calculation according to the EN 1993-1-1 is not possible because it is not suited for pressure locked gratings. The main objective of this thesis is to determine if a calculation based on the plasticity theory is possible for pressure locked gratings. Through the application of this theory the design strength can be greatly increased, which has a large economic potential. This research is divided up into four parts that are stated below. Analytical study Experimental study FEM validation Parametric study The vast diversity in size and properties and the complex functioning of the pressure locked connection make pressure locked gratings a difficult product to research. The pressure locked connection also has a big influence on the strength and stiffness. In this galvanizing has a big influence. The analytical study shows that pressure locked gratings fail through: local lateral torsional buckling of one of the load bearing bars, global lateral torsional buckling for the entire pressure locked grating or by a mechanism due to a plastic hinge in de load bearing bars. To research the behavior, numerical models were developed in the FEM-package ABAQUS. To determine the accuracy of these models, experiments were carried out on a number of pressure locked grating geometries. The results of the tests were compared with FEM simulations which made it possible to validate the FEM-models. The validation has taken place on the basis of four test series.…

▼ Wire rope is used in numerous applications such as elevators, power lines, suspension bridges, ships and the mooring of offshore structures. In many of these applications wire rope needs to be bent. Currently the Norwegian certification instance Det Norske Veritas (DNV) prescribes a capacity reduction factor for bending wire rope. It is unclear how this formula is derived or what it is based on. Therefore the main question of this thesis is: How does the forced bending of a steel wire rope around a shackle affect the break load of the wire rope? A secondary research question is: How does the forced bending of a steel wire rope relate to the reduction factor for bending enforced by DNV? These questions are answered by constructing an analytical model. In addition experiments are performed at the laboratory of the civil engineering faculty to verify this model. The analytical model is based on the assumption that every single wire behaves as an Euler-Bernoulli beam. The reduction in capacity is dominated by the effect of individual wires being bent, similar to a bundle of loose beams being bent. Plastic deformation needs to be considered to accurately describe smaller D/d ratios. Due to the helix structure, axial tension causes friction forces to develop between the strands and the wires. This increases the stiffness of the wire rope and leads to higher stresses and strains when the wire rope is bent. As soon as the wires start slipping the stiffness lowers drastically and any further deformation causes a much lower increase in stress and strain. All experiments are performed on both a 14mm and a 20mm wire rope. First an experiment is carried out to verify the test set-up and obtain the break load of a straight steel wire rope. Then a second experiment is performed to find the break load of a bent wire rope under various D/d ratios. These two tests lead to a reduction factor for bending. The analytical model shows a good fit with the experimental results. From this it can be concluded that the model developed in this thesis is a promising way to model wire rope and leads to a fairly accurate answer for the capacity reduction due to bending. The model developed and the DNV formula show similar reduction factors. For very small D/d ratios the model predicts a 5% lower reduction, while at bigger D/d ratios a higher reduction factor is predicted. The experiments show a better match with the analytical model, but due to the small differences and large standard deviation a larger sample size would be necessary to confirm this. In addition to the main question a limited investigation was done on the bending stiffness of wire rope. With some additions to the model developed for capacity reduction it was possible to model the bending stiffness. The result is a stick slip model that defines the bending stiffness as a parameter of the axial tension and the curvature, this bending stiffness rapidly declines as the wire rope is bent and wires start slipping. Although this model is not experimentally validated, the fact that the…

▼ In connections of steel structures stress concentrations occur due to the rapid geometric changes in the cross section. If the material has sufficient ductility then, due to plastic deformations, forces are redistributed so there will be equilibrium in the internal forces. In design codes this is accounted for by imposing certain requirements with respect to the tensile/yield strength ratio and minimal strain at fracture. This problem is of particular importance when high strength steels are used as questions are raised related to their ductility capacity. Over the past decades, high strength steel has gained significant ground in the steel structures market. A steel grade such as S355, which was considered to be a high strength steel 20 years ago, is now one of the predominant grades used for steel construction. In practice the occurrence of stress concentrations raises questions on how to deal with them and how to ensure a certain amount of ductility to avoid brittle fracture. In most cases an inelastic finite element analysis in shell elements and based on the nonlinear behaviour of the material is required in order to calculate the strains at the notch-tips and prove redistribution of stresses takes place. However this is a time consuming and costly procedure. This paper addresses such issues and, based on Neuber’s formula for nonlinear material behaviour, a new method is developed to calculate the strains at the locations of the stress concentrations. This new approach, entitled Stefanescu Method (SM), is based only on the results of the linear finite element analysis to estimate the value of the strains. The procedure is first developed in theory and applied to a simple case of a plate with a hole in tension because in this case the stress concentration factors are already known. The results of the SM are checked with those of an inelastic finite element analysis. Based on the simple case of a plate with a hole in tension, the SM approach gives good estimates of the strains up to a limit load value of approximately 90% of the smallest force that would cause yielding in any nominal section of the plate. The applicability of this method is extended to a bridge connection from a real life project (the A1/A6 Diemen-Almere Havendreef steel railway arch bridge developed by Iv-Infra). The method is first studied on a simplified geometry of the gusset plate from the bridge connection. As the method again yields good results it is extended to the more complex geometry of the bridge connection. Comparing the results of the SM with those of an IFEA, the method gives good estimates of the strains. Based on the models used it can be concluded that the SM method can be applied to estimate strains at the location of the stress concentrations under the conditions that the loads are known and these are below 90% of the smallest force that would cause yielding in any section of the elements subject to the stress concentrations. Also, this paper addresses the issue of the ultimate to yield strength ratio and to which extent this…

▼ Many old moveable bridges have exceeded their technical lifetime. Replacement of the foundations is expensive and often unnecessary if the new bridge superstructure is lighter than the old one. With stricter design guidelines being in effect nowadays, a conventional orthotropic steel deck design will end up being heavier. A lightweight fiber reinforced polymer deck supported by steel girders is proposed as a solution. In this thesis the potential mass reduction resulting from a lightweight FRP deck is analyzed. Analyses are initially performed under the assumption that realizing composite action will generate the best results. However, a finite element model of a bolted connection between an FRP deck and steel girders indicates that the strength of such a connection is too low to efficiently realize composite action. An alternate solution where the deck is draped over the main girders with a thin FRP layer is considered and outperforms the composite action design. The design with FRP but without composite action is compared with a standard orthotropic steel design. The FRP design weighs order of magnitude 10% less than its orthotropic counterpart. However, it is still significantly heavier than the original component in need of replacing.

▼ The high levels of wind and wave loads on offshore structures make fatigue analysis a significant parameter that has to be taken into consideration throughout an offshore structure design. Steel tubular members are widely used in offshore (wind) industry due to their efficient structural behaviour. The welded connections between the different tubular members are denoted tubular joints and they are the most susceptible locations of the structure to fatigue damage. This study is concentrated on the fatigue crack growth behaviour of tubular joints. The main objective of the thesis is the application of a procedure that predicts the fatigue crack growth behaviour in case of a tubular T-joint under axial load. This procedure relies on the basic formula of fracture mechanics approach during crack propagation (Paris law) and uses simplified geometries to simulate stress field at the vicinity of the crack and fatigue crack growth results from small-scale steel welded specimens to introduce material constants. The validity of the applied procedure is checked by fatigue crack growth tests on a realistic geometry tubular T-joints. Furthermore, the differences in fatigue crack growth behaviour between welded and base material specimens are examined as well as the effect of a single stress tensile peak on welded, base material small-scale specimens and tubular joints. The effects of stress range, stress ration, mean stress and load sequence are also included in this study.

▼ Offshore wind power provides an alternative to fossil fuels while negating the effect of visual and auditive distortion of onshore wind turbines. Located several kilometres offshore, the transmission cable resistance becomes substantial. To limit the losses, the voltage in the cables is increased in a substation. As this structure is often the largest in a wind farm, profits can be expected when optimizing this topside structure. Topside structures for the oil \& gas industry generally require to be ventilated in order to prevent gas stacking. The equipment in the substation module, however, is vulnerable for the corrosive sea environment. Therefore, the structure needs to be sheltered. Hereby, the question rises if a weight reduction can be obtained by incorporating the shelter in the structural design. The thesis is carried out at Iv-Oil \& Gas, who provided the basis of a comparative case study. For the research to be generally applicable, the case study design is simplified. Then a frame form the simplified model is chosen as a basis for the comparison. For a single governing load combination, two designs are constructed: a beam-column design complying to the conventional oil \& gas design practice and a stressed skin design that incorporates the sheltering wall as a structural element. Both of the designs are then compared on steel mass and weld labour. The stressed skin design is found to be considerably lighter than the beam-column design. However, in terms of welds, the stressed skin design consists of a higher weld volume and a higher weld pass length. These aspects contribute to the total manufacturing costs of the design. Concluding, both of the designs have their advantages and disadvantages. It is made clear that applying the dividing wall as a structural element in the format of a stressed skin design provides a competitive design in terms of structural mass and weld labour. The final conclusions based on the comparison may vary dependent on the resources available at the manufacturer.

▼ This master’s thesis is about the use of higher strength steel in buildings and the economical advantages of the use of this steel. The economical advantages are examined based on a comparison of similar designs with the use of the steel grades S355 and S460. The latter could in some cases result in large weight and cost savings. The costs are examined for trusses and columns. The trusses are applied to transfer loads from 5 different floors to columns up to 40 m apart. The columns are examined for a high-rise office with 24 stories. For all the components examined the costs have been calculated. These costs are divided into 4 different groups: Material, fabrication, transportation and assembly costs. When designing constructions with the use of S460 large material cost savings can be expected. Due to the excellent properties of this steel grade the use of S460 is beneficial for both light weight and heavy sections. For heavy sections exceptionally large material cost savings can be expected. The use of this steel grade should however be limited to axially loaded members only. Fabrication costs are more difficult to describe than the material costs. Stronger steel grades have a larger hardness which makes sawing and drilling for example more difficult. The reduced thicknesses that can be achieved by using S460 can however be assumed to compensate for this increased difficulty. Fabrication costs will ultimately not differ much from the costs required for a design with the use of S355. Assembly costs can be reduced due to the lower weight of the components. If trusses are used the total weight can be reduced significantly and the use of smaller cranes is therefore possible. The time required for construction will not change much but the costs for the required equipment could decrease significantly due to the decreased weight. The transportation costs can also be reduced because of the reduced weight. Less trucks are required to transport sections and plates to the construction site which results in a cost reduction proportional to the weight saving. The total costs for a steel structure will be lower when S460 is used. The costs for beams cannot be reduced because the use of S460 is very inefficient in these cases. A steel structure can therefore be designed with the use of S460 for the columns and S355 for beams to achieve an optimal economical design.

▼ Some storage tank terminals located in hurricane prone regions were heavily struck by hurricanes. An example is the storage tank terminal of Stolthaven Terminals (Stolt-Nielsen Limited) which is located in New-Orleans and was severely struck by Hurricane Katrina and Isaac. Damage to the terminal was caused by high wind pressures, but mainly due to flooding of the terminal caused by the overflowing levee. The storage tanks did not possess sufficient weight to counterbalance the buoyancy load generated by the flood. Due to this, storage tanks were lifted off their foundation and damage occurred to the bottom plate and the connections. Chemical liquid stored in the tank had now found its way into the environment. This disaster resulted in high costs and insurance claims from the contamination. The problem can be formulated as: "How can storage tank damage and chemical spill best be prevented during a flood?" Alternative solutions for a flood proof storage tank are presented which are applicable to the still-to-be-built new terminal next to the present terminal. Also a combination of the flood proof tank and management of tank operations is considered. 3 of the alternatives seem structurally feasible and are further elaborated in the report. These are: 1. The use of a steel-concrete-steel sandwich slab (SCS slab) inside the tank. This consists of 2 steel plates connected to a concrete core by means of shear studs. The slab should have sufficient weight to counteract the buoyancy load. [Tank alternative A] 2. Anchoring the area of the bottom plate of the tank to the concrete foundation by means of shear studs. [Tank alternative B] 3. Constructing a floating tank. This tank is provided with guiding piles, which allows the tank to go up and down, but keeps the tank at one location. [Tank alternative C] A simplified cost-benefit-analysis (CBA) is done to compare the alternatives to one of the basic solutions like the floodwall. The flood proof storage tank is compared to the basic solution (like the flood wall) a flexible alternative, because the tank does not need to be protected against floods.

▼ This study intends to develop a design method of adding more stories on existing building by using a case study of construction project in Leidschendam where 9-stories are to be added on existing 6-storey residential building. A low riser building is to be changed into multistory building. The state-of-art of the project was designed by the Engineering office of SmitWesterman and implemented by demolishing a section of the existing building where additional stories were constructed. The initial idea was to add 9-stories on existing 6 stories to form a structure of 15 story-high without demolition. Even though this idea was abandoned during implementation but it was forwarded to the
University to make further research and formulate possible design alternatives. This study is about searching a proper alternative to be used when adding storey on existing building by using lightweight materials (steel structures) without demolishing the existing structures, which are not at their maturity time. This is a proper method of changing an existing low riser into a multistory building with minimum waste. Therefore, this technique can be used in highly built environment. In this study, the major issue to be solved is to know how an existing low riser building can be changed into a multistory building. This study would have a significant effect on already built residential areas whereby more homes can be built in extremely limited place without demolishing the existing buildings. The major issues are to know the construction method to be used for this particular project, integration of the old and the new structures and the structural system to be used. This study will only cover the structural design of superstructure and foundation. As the new and old structure serve the same function, their function must be integrated but their structures may not be fully integrated. 1. Integrated design: The capacity of existing building will be checked for both superstructure and foundation. If the existing structure shows to be able to carry some loads acting on new structure, it can be mainly used to help new structure in carrying vertical and lateral loads 2. Separated design: If the capacity of existing structure cannot carry load from additional structure, the new structure will be designed differently from the existing one. 3. Partially integrated: This can be implemented in case the old building presents weakness in some structural aspects. The existing foundation is used at 40% but it cannot be used by the new structure since its weight exceeds the capacity of the existing foundation and it is impossible to add more piles. The super structure was designed to take safely only the design loads; no more floors were considered The existing building is stiff in lateral direction because all its 7 axes are filled with walls. Adding stories on existing building is possible with their function being integrated. However, their structures should be semi-integrated; they should be laterally connected for stability but the routes of vertical…

▼ A number of load modes and comfort design guidelines, with the purpose of analyzing the comfort level of target structure, has been introduced in the last few years. The approaches to these issues have in many cases been very different in both how much in detail it goes when describing the pedestrian load and to what extent the load case has to be considered. Due to the complexity of modelling the human induced load and applying the load on the structure, researches on these topics are undergoing currently. Different approaches have been provided by the two guides. The HANDBOOK 4 proposes load models for a single pedestrian, a group of pedestrians and a crowd and treats them as non-moving harmonic loads. While the British National Annex suggests load models for walking pedestrians, joggers and represents them as harmonic loads that cross the bridge at a certain speed. A widely used load model is adopted to perform more dynamic calculation so as to taking into account load cases which are not covered by the guides. 12 more load cases are considered with assumptions about the walking velocity, stripe length, the density of the pedestrians and step frequency.

▼ In the last few decades great progression has been made in the research and development of a fairly new type of concrete called ultra-high performance concrete (UHPC). This high-tech material has excellent material properties compared to conventional concrete and has the potential to make more slender and lighter structures. However the material is still very expensive and requires designers to minimize material usage in order to make an economic structure. Up to today only few structures are built using UHPC, despite that it seems that the application of UHPC has plenty of potential. Especially in long span bridges it can be a very viable solution. Because the self-weight of the structure makes up a significant part of the total loading on the structure, the material saving ability of the material has a double effect. On the one hand the material saving reduces material costs, on the other hand the material saving causes a considerable reduction of the total loading on the structure. To fully benefit from these effects, the material use should be kept to a minimum. This can be achieved by finding a structural concept that utilizes the excellent material properties of UHPC as much as possible. UHPC has a very high compressive strength combined with excellent shear capacity. Besides that it is suitable for very high levels of prestress to resist tensile forces. A study using design calculations for rectangular cross-sections have shown that the application of UHPC instead of conventional concrete leads to a significant reduction of the required volume of concrete. This holds especially for shear elements and tensile elements with a high level of prestress. Since box beams has webs as shear elements and a bottom flange as a prestressed tensile member, UHPC box beams are chosen as the best solution for long span UHPC bridges. The application of UHPC can optimize the box-shaped cross-section in several ways. Very slender beams can be made by applying a high level of prestress. Also wider beams with very thin webs can be made thanks to the high shear capacity. For this master thesis five different types of UHPC box beams are developed. These optimized box beams are designed for bridges spanning 60m, 70m, 80m, 85m and 90m. The most important advantages of these UHPC box beams over box beams made of conventional concrete are: • The beams are more slender: • The beams are wider: o Less beams have to be manufactured, transported and assembled, decreasing the amount of time and labor required to build the bridge. • The beams are lighter: o The total loading of the bridge is decreased by the lower self-weight. o They are easier to transport and to hoist. o Longer beams up to 90m can be made without exceeding the 170t weight-limit for transport by road. These benefits allow the UHPC box beams to be a fit solution for spans that are too long for conventional box beam solutions, without having to build an intermediate pier or to switch to segmented or cast in-situ solutions. Moreover they can replace old bridges with a stronger…

▼ The graduation thesis focuses on providing insight in the consequences of subsiding ground on soil anchors. With the years, the bars of an anchored sheet pile walls for example, can be unfavourably loaded due to subsiding soil. As a result of these lateral loads, the bar will deform and elongate, causing the stresses to increase. The applicability of the current design method of CUR 166 is limited. Hereby referring to using it for determining the deformation of anchors in common situations, such as inclined anchors crossing multiple layers of soil. Because of the ambiguities and limitations of this method, the report will verify and modify the design method of CUR 166. While looking at the issues regarding subsiding soil, distinction will be made between the soil behaviour around the anchor and the way in which the anchor bar deforms due to the soil load. As a way of gaining insight in the consequences of subsiding soil on anchors, Deltares has conducted model tests on small sized bars and measured the resulting loads. By simulating these tests with Plaxis 2D has the way subsiding soil loads the bars been defined. In contrast to the current method of CUR 166, the value of the shear strength should depend on the drained or undrained behavior of the soil. The result is an almost constant value for the factor to determine the load with, this in contrast to the currently used variable / unclear factor. The subsidence process loads the anchor laterally and causes it to deform. A new design method (vernieuwde rekenmethode) has been created in order to approximate the deformation and stress–strain curve of the anchor with along the free anchor length. This method is applicable for a wide range of situations, including the loading of inclined anchors crossing multiple layers of soil. The current method uses an elastic calculation to verify the stresses with the regulations. The possibilities of using a plastic calculation have been researched. Due to the displacement controlled nature of subsiding soil loading the bar, can the bending moments be absorbed by the yielding of the bar. As long as the curve of the yielding anchor bar is not obstructed by supports, the rotational capacity of the anchor will be sufficiently large to allow for yielding of the steel. In Plaxis 2D and 3D has the applicability of an embedded pile as an anchorage been researched in order to verify it with the vernieuwde rekenmethode. When comparing the different methods, it can be concluded that the resulting increase in axial anchor force due to subsiding soil, defined with the CUR 166, is conservative compared to the Plaxis simulation and the vernieuwde rekenmethode.

▼ During this thesis the fire safety engineering approach has been used to investigate the influence of hydrocarbon pool fires on steel columns. Using a fire curve which closely resembles a natural fire curve the temperatures occurring in the steel have been investigated using a Computational Fluid Dynamics (CFD) model. The model consists of the compartment which has been discussed in chapter three. As can be seen in chapter four the model which has been introduced in the CFD software closely mimics the actual compartment, including windows, roof openings and a large overhead door in the wall. After the model had been entered the fire curve must be given as well. The fire curve which has been used is based on a pool fire with a three meter diameter and a height of 2.5cm. Using the mass burning rate and rate of heat release the maximum power emitted by the liquid can be calculated. After having run the CFD calculation which took about four days per scenario the results of the temperatures in the steel had been formulated. Having used a CFD calculation the results of this calculation were to be checked by a reference tool. Arcelor Mittal has created a software package called Ozone. Having entered the same compartment and fire curve as had been done in the CFD simulation the results can be compared to each other. The results and the comparison of the two simulations have been evaluated in chapter 6.4. Focussing on the load bearing capacity of the column chapter seven investigates the maximum stress which the cross section can endure in a fire situation. Please note that this chapter only checks the strength of the column at raised temperature and omits any phenomena of instability. As the temperatures have been calculated by CFD and are thus known we can distinguish two cases. The first case is the temperature profile in the cross section of the column at which the highest temperature appears. Secondly the case in which the highest temperature difference occurs in the cross section. Having formulated a series of excel sheets an upperbound solution for the critical elastic buckling load can be calculated for columns with thermal gradients.

▼ The current calculation methods which determine the capacity of pinned connections provide different results. In this thesis a detailed look on those theories and the effect of different parameters is studied. Because it is hard to provide any conclusions about just comparing these theories also a FEM analysis is done. In this thesis the FEM model is discussed and a method is developed to analyze the FEM results. Finally some formulas are derived which predict the FEM results with an accuracy of 10%.

▼ During the design process, structural engineers are required to create more efficient designs while achieving maximum integration with other disciplines, satisfying design requirements and ensuring sufficient safety. Even though many algorithms, tools and case studies of computational optimisations for structural design are available in both literature and practice, their application is often tailored to a specific case. The limited generalizability of these optimization definitions complicates reuse of implemented design knowledge in new design situations. Even though structural design projects are unique in nature, they share a common base in terms of structural components, objectives and restraints (e.g. element strength, global structure deflection). This research proved that defining design knowledge within these abstract components allows for the reuse of definitions in new situations. This has been evaluated in three stages: 1. The development of a prototype for a knowledge-based framework, based on components, objectives and restraints; 2. The implemented knowledge was verified against reliability and efficiency of the structural design restraints and optimisation algorithms by analysing three cases; 3. Finally, the prototype has been used three complex cases to prove its versality. This resulted in a prototype of a knowledge-based framework that allows for the reuse and extension of design knowledge. In total ten case studies were evaluated with this prototype: Three basic case studies that verified conservative evaluation of load bearing resistance. Three benchmark cases that demonstrated that performance of efficient solutions found showed agreement with results in literature (maximum difference in performance 4%). A comparison of the implemented prototype with the commercial application Scia Engineer endorses the added value of the suggested approach, such as the possibility to include topology optimisation. Three complex case studies have been extensively evaluated to demonstrate the reuse of knowledge in diverse contexts, e.g., a comparative case study, a theoretic study and a practical application. Finally, prerequisites were defined for development of a knowledge-based framework that allows for the reuse of explicit knowledge for structural optimisation, such as distribution of explicit knowledge over multiple levels of abstraction, in individual generic components of the structural optimisation process (such as a structural element) with context dependent relations introduced as variables. The ability of reusing explicit knowledge allowed the author for running the ten cases in a limited time frame. It is estimated that the effort for using computational optimisation in the design process will reduce by this approach. Additional research is suggested to quantify the benefits and effort of this approach in comparison to traditional trial and error design and specialised optimisation implementations.

▼ In the Netherlands buildings are designed using a grid with multiples of 3.6 meter. Within these designs floor spans of 7.2 meter are popular (double grid size). The deep decks of composite floors at this moment in time are designed to reach an unpropped span of 5.5 meter. This master research is focused on finding a possible deck design for a steel-concrete composite floor slab that can span 7.2 m and that is constructed without the need of temporary supports. This resulted in the JorFlor, a light-weight, big span steel-concrete composite floor that can compete with current floor systems.

▼ In the need for more green energy a prominent role is reserved for wind energy. Offshore wind energy in deeper waters capitalises on more efficient wind properties and increased public acceptance compared to onshore wind energy and wind farms close to shore. In the coming years the offshore wind market is expected to evolve rapidly, especially in the deeper water range of thirty to sixty meter. In a business case preceding to this study as first reference a jacket type substructure was designed for a 6 MW turbine in a water depth of sixty meter. The goal of this thesis is to reduce the cost of this reference design in total use of material and assembly. Also the transportation and installation of the substructure are taken in consideration. First a step back is taken to reconsider the structural concept of the reference design. Several substructure concepts, like tripods and straight-leg jackets, have passed the review and firstly qualitative weighed against primary criteria in a Multi Criteria Analysis and subsequently by FEM based in-place analysis. The outcome of the total substructure weight and natural frequency with respect to frequency of wave loading and turbine excitement determined the decision to further investigate a three-leg and four-leg battered jacket. Thereto a fatigue analysis was performed. The calculation method used at the original reference design to determine the total fatigue damage due to turbine and wave loading was proven to be too optimistic and therefore modified. In relation to the reference design several optimisations have been proposed, including applying a horizontal brace just above mudline level, applying double sided butt welds and adopting K-bracing instead of X-bracing. Here the four enclosed pictures can be placed. (number 1 upmost left, number 4 upmost right) Finally, four designs have been worked out; the reference design (without optimisations), an optimised four-leg jacket, four-leg jacket with k-braces and a three-leg jacket. The total assembling cost of each design is calculated by considering the handling time and the welding volume with corresponding welding time of each weld. Together with the material use the total fabrication cost is assessed. The jacket shall be transported offshore by a standard North Sea barge. The dimensions of this barge potentially enable the transportation of three four-leg jackets and four three-leg jackets. Depending on the wind farm location this may lead to reduction of one tug and transport barge case of the three-leg jacket. Further consequence of the three-leg jacket is that a foundation pile less needs to be driven. Thereto is the installation time of the three-leg jacket reduced, resulting in less installation cost. By combining fabrication, transport and installation cost it is possible to compute an overview for substructures cost in a complete wind farm. Final conclusion is that the fabrication cost are decisive compared to the installation and transport cost. The four-leg jacket with K-braces turns out to be the most inexpensive…

▼ This thesis studies the buckling behavior of I-shaped steel columns under the effect of thermal gradients. The mechanical properties of steel decay signicantly with increasing temperature. Therefore, in case of a re, the buckling resistance of steel columns is considerably reduced due to the decrease in the modulus of elasticity and yield strength. Furthermore, in a realistic re scenario, temperature gradients develop throughout the cross-section and throughout the column's length. However, the design guidelines in Eurocode 1993-1-2, as well as in other leading construction codes, specify that in the case of a non-uniform temperature distribution the column's buckling resistance must be determined by considering a uniform temperature distribution considering the maximum temperature in the cross-section. The objective of this thesis is to assess the reliability of the provisions given by the Eurocode for elevated temperature design in the presence of temperature gradients. A series of finite element models were created for five different cross-sections and analyzed at room temperature, uniform elevated temperature and non-uniform temperature along the cross-section. From the uniform elevated temperature analysis, a buckling curve for elevated temperature was derived. The finite element analysis results for the models under the effect of temperature gradients showed better agreement with this FEM-derived buckling curve than with the Eurocode provisions, which were shown to be over-conservative for the case of a temperature gradient along the column's weak axis. The FEM results were also compared to the results obtained with the American and Australian building codes

▼ Dynamics of railway bridges is a complicated problem that normally needs nu- merical simulation to conduct researches on. However, this thesis takes advan- tage of the numerical results provided in previous researches and based on these researches, further conclusions are made by using them in simplified model. Recently long span railway bridges being designed in the Netherlands are being rejected by a particular Eurocode criterion that requires bridges to possess a first lateral natural frequency higher than 1.2Hz. Due to the fact that generally bridge’s first lateral natural frequency decreases as the span increases, it can be seen that 1.2Hz criterion is rejecting almost all bridge with a span longer than 150m. This report succeeds in pursuing the original documents of 1.2Hz criterion and the knowledge in the documents initiates further researches on the lateral dy- namics of railway bridges. Besides 1.2Hz criterion itself, following topics are researched with the information provided by previous researches: 1. Train-bridge lateral resonance mechanisms, including axle repeat pattern resonance and kinematic movement resonance, 2. Lateral force on tracks caused by the operation of railway vehicle and key parameters influencing the force. Taking advantage of the items above, a simplified model for checking the lateral railway bridge dynamics is developed to quantify the lateral dynamic resonance response of railway bridge under horizontal dynamic vehicle load. This method aims to serve for engineering purposes and provide an alternative way of ver- ifying railway bridge lateral dynamics. The practical method is developed by an analytical approach, based on the numerical simulation results provided by other researches. An illustration of the usage of the practical method is conducted on the basis of a real bridge project. The method is also implemented in Matlab scripts to automate the checking procedure.

▼ Een stalen plaatligger is een hoog I-profiel samengesteld uit stalen platen die aan elkaar worden gelast of gebout. Stalen plaatliggers kunnen geplaatst worden als dakligger in industriehallen. Het toepassen van een stalen plaatligger in plaats van een raatligger of vakwerkligger kan in economisch opzicht de optimale keuze zijn. Door het verhogen van de maximale lijfslankheid van liggers kan het staal efficiënter in de doorsnede worden geplaatst. Er zijn echter redenen om kritisch naar de brandwerendheid van slanke plaatliggers te kijken. De redenen waarom aangenomen mag worden dat een ligger met hogere lijfslankheid negatieve gevolgen heeft voor de brandwerendheid zijn: De profielfactor van de stalen plaatligger zal worden verhoogd. Door een snellere opwarming zal de kritieke staaltemperatuur eerder worden bereikt waardoor de ligger relatief snel zal bezwijken; Vanwege stabiliteitsproblemen is het aannemelijk dat de kritieke staaltemperatuur van plaatliggers met hoge lijfslankheid tijdens een brand snel zal worden bereikt. In dit afstudeeronderzoek zijn de gevolgen van het slanker maken van het lijf van stalen plaatliggers voor de brandwerendheid onderzocht. In het kader van dit onderzoek is gekeken naar een stalen plaatligger toegepast als dakligger in een industriehal. Een hoge lijfslankheid zal, zoals is aangetoond in dit onderzoek, veelal leiden tot een hoge profielfactor (Am/V). De standaard-brandwerendheid van stalen plaatliggers met een profielfactor groter dan 250 m-1 is minder dan 10 minuten (en volgens de werkhypothese zoals gesteld in het verslag onvoldoende). Voor zeer slanke plaatliggers kan een profielfactor groter dan 350 m-1 worden verwacht. Dit is dus onvoldoende om zonder aanvullende voorzieningen veilig te kunnen worden toegepast in een industriehal. Het is noodzakelijk om kritisch te kijken naar de brandwerendheid van stalen plaatliggers met hoge lijfslankheid. Door een model op te stellen van een meer realistisch verloop van de temperatuur in een brandcompartiment is vast gesteld welke tijd de staaltemperatuur onder de kritieke staaltemperatuur van doorsnedeklasse 4 profielen zal blijven. In dit onderzoek is het verloop onderzocht van de temperatuur in een groot brandcompartiment (35m breed, 40m lang, 8m hoog). Aangetoond is dat de tijd voor het bereiken van de kritieke staaltemperatuur sterk afhankelijk is van de uitbreidingsnelheid van de brand. De branduitbreidingssnelheid wordt gekarakteriseerd door de tijd waarin de oppervlakte van de brand gegroeid is tot een oppervlakte met een effectieve hoeveelheid warmte afgifte van 1 MW, de zogenaamde tijdconstante (t?). Een lage tijdconstante betekent een snelle branduitbreiding. In het gekozen brandcompartiment wordt de kritieke staaltemperatuur (van 350 °C) bereikt na 20 minuten (na ontsteking) bij een tijdconstante (t?) van 160 seconden. Bij deze tijdconstante hebben de gebruikers (volgens een vastgestelde werkhypothese) voldoende tijd om uit het gebouw te vluchten, en de brandweer het gebouw te doorzoeken. Indien de industriehal wordt gevuld…

▼ Design of a lock gate for Nieuwe Zeesluis in IJmuiden becomes a challenge when the boundary conditions limit the choice for the conventional types of the gate. The available width of the lock does not allow a straight rolling gate to be considered as a possible alternative as it is in most similar cases. All the initial efforts of this study have been made in search of a new alternative to solve the space limit problem. After assessment of a number of feasible type of gates, finally, when the curved gate concept was introduced based on the concept of rolling gates and sliding gates, all the functional requirements of the design had to be met. This study investigates in three different structural alternatives for the curved gate in the concept development stage as well as three different operating systems and two different supporting systems. Based on certain design objectives, a final concept is chosen and is developed into a preliminary design. The design objective have been defined based a simple criteria of achieving the most benefit with the lowest investment possible. In this manner it is tried to increase the functionality of the design for gate structure. These objectives are basically: - Minimum use of movable devices - Minimum necessity of maintenance - Innovation - Simplicity The main challenge in the conceptual design is to find the optimum combination within the alternatives for the main compartments of the gate while every advantageous solution for a compartment, introduces a new problem in another. For making a better decision a framework is defined for the evaluation of the solutions and alternatives with the help of a score system which enables us to see which alternative is in line with the design objectives the most. Furthermore, the study presents a rather detailed design of certain compartments such as operational equipment, guidance devices, tracks, hydraulic bearings and sealing system. Structural and stability checks are done for the extreme load conditions, loads during the special combined movement and construction of the gate. This results in a preliminary design which is integrated and consistent in satisfying all the functional requirements of the design. The final and most important evaluation of the research study discusses the costs, safety, reliability and availability of the gate structure by means of a qualitative RAMS analysis accompanied by a cost comparison table. These two outcomes provide insight on applicability of the gate into the different situations but especially in this case study. This report will discuss the approach and steps in which the idea was developed and it answers the feasibility and applicability questions by the help of final results and evaluations. Report ends with presenting the conclusions of the work and giving a number of recommendations.

▼ The United States of America – and more specific the state of Illinois – are dealing with a problem of Asian carps spreading from inward waterways to the Great Lakes. The Asian carp was originally brought to America to be used in study?s on agricultural pounds, but escaped after series of flooding. The Asian carp has no natural enemies in the waters of the United States and are heading via the Mississippi River to the Great Lakes.The threat of the Asian carp lies in the special? property that these fish have a large appetite and tend to eat everything in their way which is smaller than them. They reproduce rapidly which means that in relatively short periods entire areas can be cleared from plankton and aquatic plants. Their presence can ruin entire vegetation?s and especially when the would enter the Great Lakes, huge economic and environmental problems could arise. Due to these imminent problems multiple studies have been made to stop these fish, but yet so far no actual solution has come up. Even an electrical curtain wasn?t able to stop them. The only connection between the Mississippi River and the Great Lakes – the Chicago Sanitary and Ship Canal – is a perfect location for a structure that can stop these fish, but still allowing the inland water vessels to gain access to Chicago and the Great Lakes. This canal is designed as part of the sewage system of the Chicago Area Waterway System and is needed to remain a proper water quality – closing this canal off will lead to large investments in multiple wastewater treatment plants. A proper solution is therefore desired which lead to an passage for vessels without providing a passage for fish heading upstream towards the Great Lakes. A surroundings and stakeholders analysis showed that the best location for such a solution will be in the Chicago Sanitary and Ship Canal near the place Lockport. Meeting the requirements the best solution for this problem is the design of a water-free vertical boat lift?. This design can be combined with the renovation/renewing of the current Lockport lock in the canal. The water-free vertical boat lift has similarities with a regular vertical boat lift, but has the special property that it lifts the vessels to the upstream water level without the help of water. A vessels will enter the lock chamber via two vertical lifting doors whereafter the water is drained out of it. The vessel will the lower until it rests on inflatable rubber bags on the floor. Hereby all the water and fish will be caught in a water storage area underneath the lock chamber from where the water and fish will be released downstream again. Afterwards the empty lock chamber with the vessel will be lifted to the upstream water level from where water can be pumped back in and the vessel can continue. The lock chamber is made out of steel walls of 7,5 meters high in combination with a steel/concrete combined floor of 18,5 meters width and 100 meters length. The concrete slab will be inclined to gain a 1:20 slope for a proper outflow of the water and fish. The…

▼ Volgens de Hydraulische Randvoorwaarden van 2001 moeten de Nederlandse Rijntakken vanaf 2015 in staat zijn om een Maatgevende Hoogwater (MHW)-golf van 16.000 m3/s veilig naar zee af te voeren. De voorspelling is dat de MHW-golf in de nabije toekomst (2050) zelfs nog verder toe zal nemen tot 18.000 m3/s. Op dit moment is de eis 'slechts' 15.000 m3/s. Het huidige rivierstelsel heeft niet genoeg capaciteit om het toegenomen debiet veilig naar zee af te kunnen voeren. Daarom is het treffen van maatregelen noodzakelijk. Evan de mogelijke oplossingen voor dit capaciteitsprobleem is het beloeden van de afvoerverdeling waardoor de maximale capaciteit van het rivierstelsel benut kan worden. Dit wordt gedaan door de optredende verstoringen in de met computermodellen voorspelde afvoerverdeling te corrigeren naar de gewenste (optimale) afvoerverdeling. Bij overschrijding van het MHW kan er voor gekozen worden het extra debiet naar riviertak te sturen, om zodoende overstromingen benedenstrooms van het splitsingspunt tot tak te beperken. In dit afstudeerwerk is gezocht naar maatregelen waarmee de afvoerverdeling op het splitsingspunt Pannerdensche Kop (zie figuur), tijdens MHW, gecorrigeerd kan worden. Veder is gekeken naar de mogelijkheid om bij afvoeren groter dan MHW het extra debiet richting riviertak te sturen. Met behulp van een hydraulisch model gebaseerd op een afgeleide van de vergelijking van Bernoulli waarin energieverliezen in rekening gebracht kunnen worden en met behulp van het 1D model Sobek is een aantal alternatieven onderzocht. De belangrijkste conclusies van dit onderzoek zijn dat weerstandsverhogende maatregelen, zoals een flipper op het splitsingspunt of stuwen en kleppen op de benedenstroomse riviertakken, grote opstuwing en hoge stroomsnelheden veroorzaken. Daarnaast zijn de benodigde afmetingen van de constructie waarmee voldoende gestuurd kan worden groots en is realisatie dus duur. Weerstandverlagende oplossingen blijken lokaal weinig invloed te kunnen uitoefenen. De invloed van de lange benedenstroomse riviertakken is dermate groot dat lokale wijzigingen vrijwel tenietgedaan worden. Weerstandsverlagende oplossingen uitgestrekt over een grotere lengte, zoals nevengeulen, kunnen wel voldoende sturen en veroorzaken in plaats van opstuwing een waterstandsverlaging. Helaas neemt een dergelijke maatregel erg veel ruimte in beslag. Daarnaast blijkt uit een globale kostenraming gebaseerd op de constructieve uitwerking van dit alternatief, dat de aanleg van de benodigde nevengeulen 3,2 tot 4,8 miljard Euro kost. Eindconclusie van dit afstudeerwerk is daarom dat er geen maatregel gevonden is waarmee zonder optreden van grote negatieve hydraulische neveneffecten en zonder grote maatschappelijke impact, op een financieel haalbare manier, een voldoende groot debiet op de splitsingspunten van richting veranderd kan worden.

▼ In tegenstelling tot de meeste waterbouwkundige constructies is de hoofdfunctie van een schutsluis niet uitsluitend de waterkerende functie. Een evenzo belangrijke functie van een schutsluis is vaak de verkeersfunctie. Dit betekent tevens dat er meer en andere partijen, met elk hun eigen wensen en eisen, betrokken zijn bij het systeem. Zo zal de beheerder / opdrachtgever gebaat zijn bij lage bouw- en onderhoudskosten en zal de beroepsvaart een zo groot mogelijke capaciteit van de schutsluis willen. Deze dualiteit tussen enerzijds bouw- en onderhoudskosten en anderzijds wachtkosten van het verkeer en kosten niet-beschikbaarheid zijn van de hoofdoorzaken waarom het ontwerpen van een schutsluis zon complexe aangelegenheid is. Een tweede probleem is dat niet alle kosten op hetzelfde moment worden gemaakt. Zo zullen de aanlegkosten aan het begin van de levensduur vallen, terwijl de overige kosten verspreid over de gehele levensduur van de sluis zijn. Er is daarom gekozen om alle kosten tijdsneutraal te maken, zodat een realistische kostenanalyse kan plaatsvinden. Bij het ontwerpproces van een civieltechnische constructie staat de mens als ontwerper centraal. Dit betekent dat al in een vroeg stadium van het ontwerpproces bepaalde ontwerpvarianten worden uitgesloten. Door de dualiteit tussen kosten en functionaliteit is het echter lastig om te bepalen welke vormvarianten afvallen. Een variant kan bijvoorbeeld uit oogpunt van bouwkosten zeer positief zijn, maar kan vervolgens weer nadelige gevolgen hebben voor de capaciteit van de schutsluis. Het optimale ontwerp is een subjectief begrip. Voor de beheerder / opdrachtgever zal dit het ontwerp met de laagste bouwkosten zijn en voor de gebruiker zal dit een schutsluis zijn met voldoende capaciteit. Er is bij dit model gekozen om alles zo veel mogelijk te kwantificeren en op basis van de totale levensduurkosten een uitspraak te doen over het optimale ontwerp. De kosten kunnen op twee manieren worden beloed. Ten eerste kan de vorm van de gehele sluis of van delen van de sluis worden gewijzigd. Ten tweede kunnen de afmetingen van onderdelen van de sluis worden gevarieerd. Met name de afmetingen van de schutkolk zijn hierbij van belang. In het model zal een groot aantal varianten worden doorgerekend die zowel qua vorm als qua afmetingen van elkaar verschillen. De totale levensduurkosten zijn opgebouwd uit de realisatiekosten, onderhoudskosten en reparatiekosten van de schutsluis, wachtkosten van het scheepvaart- en wegverkeer, kosten van niet-beschikbaarheid en de kosten van de sloop van de schutsluis. Kosten van niet-beschikbaarheid zijn de kosten, die ontstaan doordat de sluis tijdelijk buiten gebruik is, bijvoorbeeld door calamiteiten of onderhoudswerkzaamheden. De capaciteit van de schutsluis wordt hoofdzakelijk bepaald door de lengte van de kolk (Lkolk) en de breedte van de kolk (Bkolk). Alle andere parameters van het ruimtelijk ontwerp zijn gerelateerd aan deze twee parameters. Door de complexe relaties tussen aanlegkosten en gebruikskosten zijn de twee ontwerpparameters…

▼ Historisch gezien loopt de ontwikkeling van woontorens achter op die van kantoorgebouwen, voornamelijk omdat voor woontorens doorgaans een geringer budget beschikbaar is. De laatste jaren is deze tendens aan het omslaan, de kantoormarkt is zo goed als verzadigd en de vraag naar woningen op hoog niveau, zowel qua hoogte als qua comfort, neemt toe. Nationaal gezien is vooral Rotterdam de laatste jaren erg succesvol met de bouw van woontorens. En deze trend zet zich voort, onder andere in het plan voor een hoge woontoren aan het Oostplein. In opdracht van de ontwikkelingscombinatie Vesteda, Innoplan en J.P. van Eesteren heeft Hubert-Jan Henket architecten een ontwerp gemaakt voor deze toren. Dit ontwerp bestaat uit een plintgebouw in de stijl van de omliggende bebouwing, waarboven een slanke solitaire woontoren verrijst, die als het ware zweeft boven het plintgebouw. In het architectonische plan schuilen een aantal constructieve uitdagingen, waarvan het creëren van deze zwevende beleving en de aanwezigheid van twee grote ondergrondse afwateringskanalen de belangrijkste zijn. Het afstudeerwerk heeft als doel een constructief ontwerp te maken voor woontoren Oostplein, waarbij het architectonische ontwerp, de constructieve logica en de uitvoering de leidende factoren zijn. Om te komen tot een dergelijk constructief ontwerp is een alternatievenstudie uitgevoerd naar verschillende typen hoofddraagconstructies. In dit eindrapport is het gekozen alternatief kernconstructie op een gedetailleerde wijze uitgewerkt. Hierbij is zowel voor de fundering als voor de bovenbouw een eindige elementen model gemaakt. Aan de hand van de resultaten uit deze modellen wordt het constructieve gedrag van de hoofddraagconstructie bepaald. In de alternatievenstudie zijn vier typen hoofddraagconstructies geanalyseerd. De ondersteunde kernconstructie is niet te combineren met de plannen voor een spiraalvormige parkeergarage rond de kern. Voor de keuze tussen de overige drie alternatieven is een Multi Criteria Analyse uitgevoerd. Hierin scoort de kernconstructie hoog vanuit functioneel en architectonisch oogpunt en de outrigger en de gevelbuis scoren hoog vanuit constructief oogpunt. De keuze voor uitwerking van de kernconstructie is mede gebaseerd op het feit dat het functionerende afwateringskanaal tijdelijk of definitief omgelegd kan worden, waardoor de inpassing van de fundering mogelijk wordt gemaakt. Bovendien geniet dit alternatief de voorkeur van de ontwikkelingscombinatie.

▼ In de praktijk worden steeds meer gebouwen vervaardigd uit geprefabriceerde betonelementen. Deze elementen worden in de fabriek gemaakt waarna ze worden getransporteerd naar de bouwplaats. Op de bouwplaats worden deze onderdelen aan elkaar bevestigd. Deze werkwijze bespaart tijd in de uitvoeringsfase ten opzichte van traditionele betonbouw (bouwen met ter plaatse gestort beton). Op de bouw is het vaak wenselijk dat het aantal handelingen beperkt blijft. Om dit te kunnen bereiken worden de verbindingen vaak scharnierend uitgevoerd. De elementen hoeven dan alleen op hun juiste positie te worden geplaatst en bevestigd. Onder normale omstandigheden zullen er geen problemen optreden met een geprefabriceerde constructie. Interessant wordt het wanneer er een bijzondere belasting aangrijpt op de constructie, bijvoorbeeld een gasexplosie. Het optreden van een gasexplosie kan ervoor zorgen dat een element bezwijkt. In de traditionele bouw met monolietconstructies is herverdeling van krachten wanneer een draagelement bezwijkt mogelijk. Voor geprefabriceerde betonconstructies met scharnierende verbindingen is dat niet het geval. Het bezwijken van elementen kan voortschrijdend instorten van de constructie tot gevolg hebben. Een constructieve oorzaak voor het voortschrijdend instorten van constructies is het ontbreken van voldoende incasseringsvermogen van constructies. Onder incasseringsvermogen wordt verstaan de weerstand die de constructie levert tegen de optredende belastingen. Het bezwijken van één element kan ervoor zorgen dat een deel van de draagconstructie instort. Het volume van de draagconstructie dat bezwijkt, moet zo beperkt mogelijk zijn. Er zal dus moeten worden gezocht naar constructieve mogelijkheden om het incasseringsvermogen van de constructie te verhogen. Het doel van dit onderzoek is het vinden van constructieve methoden om het incasseringsvermogen in constructies te verhogen bij een gasexplosie plaatsvindt. In de nieuwe norm prEN 1991-1-7, worden wel rekenregels gegeven betreffende voortschrijdende instorting. Het is dus zaak dat deze regels op de juiste wijze worden toegepast in de praktijk. Daarom wordt er ook onderzocht in hoeverre die regels geldig zijn. In dit onderzoek is de constructieve samenhang onderzocht na een gasexplosie aan de hand van een een modelgebouw. In dat modelgebouw zijn alleen geprefabriceerde betonelementen toegepast. Er zijn twee varianten bekeken. In variant 1 bestaat de constructie uit kolommen, balken en kanaalplaatvloeren. In variant 2 bestaat de constructie uit wanden en kanaalplaatvloeren.
