▼ In predicting the likely behaviour of precast prestressed concrete flooring systems in fire using advanced finite element methods, an improved numerical model using the non-linear finite element program SAFIR has been developed in order to investigate the effects and the interaction of the surrounding structures and has been used extensively throughout this thesis. Note that fire induced spalling is not included in the analysis. In the numerical investigation of the new model, the reinforced concrete topping is modelled as part of the beam elements in order to predict the behaviour of single hollowcore concrete slabs, with various support conditions, under a Standard ISO fire. It is shown that the current approach using tendons that are anchored into the supporting beams leads to a major problem for precast prestressed flooring systems. In order to resolve this problem, a multi-spring connection model has been developed to include the old and new connection systems corresponding to the New Zealand Concrete Standard NZS 3101. The connection model with hollowcore slabs is validated against a published fire test. The investigation on restrained hollowcore floors is performed with various parameters and boundary support conditions. Numerical studies on various boundary support conditions show that the behaviour of hollowcore floors in fire is very sensitive to the existence of side beams. Further investigations on the effects of fire emergency beams, which reduce the transverse curvature of floors to improve fire resistance, are made on 4x1 multi-bay hollowcore floors with different arrangements of theses beams. The numerical studies show that fire emergency beams significantly increase the fire resistance. Code based equations which can calculate the shear resistance and splitting resistance are then introduced. The Eurocode equation can be modified with high temperature material properties to estimate the shear capacity of a hollowcore slab. The modified Eurocode equation which is fit to fire situations validated against the published literature with respect to shear tests in fire. The structural behaviour of single tee slabs having different axial restraint stiffness as well as the variation of axial thrust in fire is then studied. SAFIR analyses of single tee slabs show that fire performance can increase when a web support type is used that has high axial restraint stiffness. A series of test results on prestressed flat slabs conducted in United States are used to validate a simply supported numerical model. The application of multi-spring connection elements is also investigated in order to examine the feasibility of continuity.

▼ This thesis presents the results of research on sandwich panel construction, with the aims of developing tools for modelling sandwich panel fire performance and hence to use the tools to aid the development of sandwich panel construction with improved fire resistance. The research focuses on sandwich panels made of thin steel sheeting and a polyisocyanurate (PIR) foam core. For non-loadbearing sandwich panel construction, fire resistance is measured in terms of thermal insulation and integrity only. However, these two parameters are affected by mechanical performance of sandwich panel construction due to the high distortion and large deformation nature of sandwich panel construction under fire attack. Therefore, it is necessary to consider both thermal and mechanical performances of sandwich panels under fire conditions. The work in this thesis includes development of a thermal conductivity model for PIR foam as this thermal property is one of the key values in determining heat transfer through sandwich panels; this thermal conductivity model is based on the effective thermal conductivity of porous foams proposed by Glicksman (1994) and includes the effects of polymer decomposition and increases in foam cell size. It is validated against fire tests carried out on PIR sandwich panels 80mm and 100mm thick with steel facings of thickness 0.5mm. A large 3D sequentially coupled thermal-stress model of a full scale fire test has been developed in the commercial finite element analysis (FEA) software ABAQUS to provide insight into the way sandwich panels behave in a fire resistance test and also to assess different modelling techniques. Aspects and stages of the simulation that agree well with test data are explained. Limitations of the ABAQUS software for simulating sandwich panel fire tests are highlighted; namely, it is not possible to simulate the correct radiation heat transfer through panel joints, as cavity radiation cannot be specified in a fully coupled thermal-stress analysis. Joints are key components of sandwich panel construction. In order to obtain temperature development data for modelling joints, a number of fire tests have been carried out. These fire tests were conducted with different joint configurations and panel thicknesses under realistic fire conditions using timber cribs. The joint fire tests revealed significant ablation of the foam core within the joints of sandwich panels at high temperatures. At the beginning of fire exposure, the joint temperature on the unexposed surface was lower than that on the panel due to the better insulation property of air compared to the foam. However, as the joint gap increased due to ablation of the foam, the joint temperatures became higher than in the panel. A numerical simulation model has been created to investigate this behaviour. Using the aforementioned thermal model, numerical simulations have been carried out to examine the influences of possible changes to sandwich panel design on sandwich panel construction fire performance. It was suggested that if the…

▼ Post-tensioned timber frames have recently been undergoing heavy research and development at the University of Canterbury. The recently developed post-tensioned timber system utilises engineering wood products such as Laminated Veneer Lumber (LVL) and glue laminated timber (Glulam), which are formed into box sections and post-tensioned with high strength steel tendons made from stranded steel wire or solid steel bars. The post-tensioning serves to counteract some of the bending actions imposed on the timber beam from loading through a variety of mechanisms. Previous research has focused on the seismic performance and gravity frame performance of post-tensioned timber, both of which yielded promising results. There is however a commonly perceived increase in fire risk with timber building, particularly multi-storey timber buildings, and the fire performance of post-tensioned timber had not previously been investigated. Therefore, the focus of this research was to investigate the fire performance of post-tensioned timber beams. This was completed through a series of full-scale furnace tests, and the development of a fire resistance design method. Three 4.36m span post-tensioned timber beams were exposed to the ISO 834 standard fire. Each of the test beams were glued box beams made from 63mm LVL and were of varying external dimensions. Each beam was intended to demonstrate a specific failure mechanism at approximately 60 minutes of fire exposure. The failure mechanisms demonstrated were a shear failure in the lower corner of due to corner rounding, and a combined bending and compression failure at the end of the beam. These failure mechanisms are unique to post-tensioned timber in fire. The results of the experimental testing were used to validate and refine the proposed fire resistance calculation. Also tested during the full-scale testing were five different forms of anchorage fire protection. These were tested as a secondary objective, but useful thermal data was collected. Through the full-scale testing and the calculation method development it was found that it is important to consider shear during fire design. The post-tensioning increases the bending capacity of a beam but doesn’t affect its shear capacity, therefore when more loading is applied to utilise the increased bending capacity the shear action is increased which leads to shear governing the design in many cases. It is also important to consider shear not only in the webs at the centroid where the shear flow is greatest but also in the lower corners, which can become much thinner than the webs. Without calculation it is not possible to determine where the shear stress will be greatest and therefore both the web and the lower corners need to be checked. It was also found that as the timber section chars on three sides the post-tensioning eccentricity increases which can lead…

More and more high-rise buildings are being built of wood, largely because of thedevelopment of factory-manufactured industrial building elements and building systems inrecent years. Despite great positive impact on the environmental impact of the constructionindustry, the fact remains that wood burns very easily, and spreads quickly unless the rightmeasures are taken at the design stage.The purpose of this study is to investigate how high wooden houses are protected againstfire during the design phase. The new function-based requirements from BBR opened upnew opportunities to build high in wood. The idea is to highlight and inform about therelatively new way of building high-rise buildings with the fire factor in focus.Interviews and literature studies formed the basis for this study of the effective methodsused in the design of tall wooden houses.The design is drastically affected if the frame is built of wood material. BBR, the FireBrigade and insurance companies are some of the experts consulted in connection withthis study. Information from Fire Engineers and Designers allowed us to see how fire isprevented and what changes are being made unlike houses of other materials.The literature study and interviews show that fire risks for these types of buildings areovercome after the implementation of all BBR regulations and laws with analytical designfor fire protection in Br0 buildings. Sensitive designs must be addressed through the use ofappropriate sealants around the throughings, secure fire cells with various disks such asplasterboard, non-combustible materials such as mineral wool can be used as insulatingmaterials, mechanical ventilation systems that can reduce fire spread through ventilationopenings, and automatic with manual fire extinguishers that can meet the requirements.The conclusion is that fire can definitely be prevented in the design of tall wooden housesby using the solutions we present in connection with this study.

Allt fler höghus byggs av trä, tills största del är det på grund av senaste årens utveckling avfabrikstillverkade industriella byggelement och byggsystem. Trots stor positiv inverkan påmiljöbelastningen från byggbranschen återstår faktum att trä brinner väldigt lätt, och spridssnabbt om inte rätt åtgärder tas vid projekteringsskedet.Syftet med denna studie är att undersöka hur höga trähus skyddas mot brand underprojekteringsskedet. De nya funktionsbaserade kraven från BBR öppnade upp nyamöjligheter att bygga högt i trä. Tanken är att belysa och informera om det relativt nyasättet att bygga höghus med brand faktorn i fokus.Intervjuer och litteraturstudier stod som grund för denna undersökning av de effektivametoderna som används vid projektering av höga trähus.Projekteringen påverkas drastiskt om stommen byggs av trämaterial. BBR, Brandkårenoch försäkringsbolag är några av experterna som har hörts i samband med denna studie.Information från Brandingenjörer och konstruktörer tillät oss att se hur brand förebyggs ochvilka ändringar som genomförs till skillnad från hus av…

▼ This thesis provides a computational investigation of three separate composite steelbeam fire tests conducted at Lehigh University’s ATLSS Laboratory as well as parametricanalyses with various fire curves and levels of passive protection. The objective of thisstudy was to validate numerical models that conservatively capture structural failure ofcomposite floors subjected to fire, while striving for simplicity, to help further realizeperformance-based design and evaluation approaches for structural-fire resistance andresilience of secondary floor framing in steel buildings.The first pair of tests were identical structural systems with one having passive fireprotection and the other being unprotected subjected to the ASTM E119 fire curve.Thermal analysis of the steel was performed using a lumped mass approach, which can beimplemented via spreadsheet or a simple, explicit programmed solution. Thermal analysisof the slab was performed using a simple one-dimensional heat flow model. Two types offinite element analyses were performed: one composed of shell elements and anothercomposed of fiber-beam elements. The slab was unrestrained in all cases, so the effects ofslab continuity and membrane action were neglected. The structural models referencedboth lumped mass prediction temperatures as well as measured test temperatures as inputfor the temperature-dependent material properties of the specimens. The results of allmodels show conservative agreement with the experimentally observed behavior. Theplasticity of the section is analyzed over the duration of the tests using the concept ofwarping axial-moment failure envelopes which consider shifting of the effective centroiddue to the thermal gradient per three-sided heating. These models can be leveraged as part of a conservative performance-based approach to design composite floor assemblies forone-way flexural behavior under fire.The final validation case consisted of an unprotected composite beam subjected toa realistic fire curve with a decay phase. The objective of this study was to point towardsthe possibility of surviving a realistic fire scenario with a decay phase, as opposed to thecontinued growth of the ASTM E119 curve. The test fire curve closely matches the E119fire for 20 minutes prior to rapidly decaying. The test beam was shown to withstand theparametric fire curve computationally, resulting in relatively little damage, matching thetest observations reported. According to the ASTM E119 thermal criteria, the beam“failed” around 13 minutes. The same pair of SAFIR finite element models used in therunaway failure model validation were used to compare structural behavior of an assemblywhen it is permitted to cool in the case of fire suppression.The models of the realistic fire test were then parametrically extended to variouscombinations of active and passive protection, as well as different fire curve formulations.The fact that these models could capture failure per the first validation study allowed forthis extension to be confidently applied. The model… Advisors/Committee Members: Quiel, Spencer E..

▼ The advantages of cold-formed thin-walled steel studs are many and their applications in building constructions continue to grow. They are used as load-bearing members. An example is lightweight wall panel assemblies which consist of channel steel studs with gypsum plasterboard layers attached to the two flanges, often with interior insulation. At present, expensive fire tests or advanced numerical modelling methods are necessary in order to discover the fire resistance of such wall assemblies. For common practice this is not effective and a simplified method, suitable for use in daily design, is necessary. The aim of this research is to develop such simplified methods. The first main objective of this study is to develop a simple approach to calculate the temperature distributions in the steel section, in particular the temperatures on both the exposed and unexposed sides when the panel is exposed to fire exposure from one side. These two temperatures are the most influential factors in the fire resistance of this type of wall assembly. The proposed method calculates the average temperatures in the flanges of the steel section and assumes that the temperature in the web is linear. The proposed method is based on a simple heat balance analysis for a few nodes representing the key components of the wall panel. The thermal resistance of these nodes are obtained by the weighted average of thermal resistances in an effective width of the panel within which heat transfer in the panel width direction is assumed to occur. The proposed method has been extensively validated by comparison with numerical parametric studies. In order to calculate the ultimate capacity of steel studs, the traditional method is by using effective width. However, this method is now being questioned as it considers elements of section in isolation and does not consider interaction between the elements. In addition, this method is not appropriate to be extended to steel studs under fire conditions. The cross-section under fire conditions has non-uniform temperature distribution which results in the non-uniform distribution of mechanical properties. Using an effective width method to deal with this problem will require many assumptions whose accuracy is uncertain. Recently, the direct strength method (DSM) has been developed and its accuracy for ambient applications has been comprehensively validated. This method calculates cross-sectional plastic resistance and elastic critical loads for local, distortional and global buckling modes with the aid of simple computer programs. The elastic and plastic resistances are then combined to give the ultimate resistance of the structure using interaction equations. This method is suited to steel studs with non-uniform temperature distribution in the cross-section. The second main objective of this study is to extend the direct strength method for application to thin-walled steel studs having non-uniform elevated temperature distributions in the cross-section. It has been found that the DSM concept is applicable,…

▼ In bridge design, extreme hazards have been considered as design loads for years, including wind, earthquake, snow, and floods; but fire hazard is not usually considered in the design process. However, severe fire accidents occurring near or under bridges are not as rare as generally perceived compared to the other extreme hazards, especially earthquakes and floods. Therefore fire resistance of bridges along the most critical arteries of transport networks, carrying heavy traffic, should be considered. This should ideally be based upon an estimation of the consequences of a particular level of bridge damage in terms of social and economic costs. Since there are no codes or standards relating to fire resistance of bridges, assessment must rely upon a performance-based engineering approach. In conducting performance-based studies of bridge fire resistance, most previous researchers have used code-based fire curves, such as the ISO 834 standard or Hydrocarbon fires, which assume uniform heating along the entire bridge span. However, a real vehicle fire will naturally create a non-uniform, localised fire under the bridge span and the hazard intensity will decay with distance away from the burning vehicle. If such a scenario could be implemented in a more realistic fire model, then more realistic thermal and thermo-mechanical response of structures could be predicted, resulting in more reliable estimates of performance. This thesis consists of three main parts. Part I investigates the structural performance of composite steel-framed bridges and the influence of bridge shape on failure time under code-based Hydrocarbon fire loading. Part II uses the CFD-based fire dynamics simulation code FDS to generate design fire curves for four different classes of vehicles. The design fire curves include the expected decay in the intensity of the heat flux due to the fire along the bridge span. These curves were then generalised as mathematical functions that can be easily used by engineers and designers in the assessment of the performance of existing bridges under realistic hazard scenarios, for fire resistance design. Rectangular bridge models were subjected to the most extreme class of design fire (fuel tanker fires) in order to compare with the Hydrocarbon fire. The analysis showed that, for the bridge structure considered, there is no failure for the model in the fuel tanker fire scenario, even with conservative assumptions. However, failure may occur if a higher heat release rate is used, which is possible for large fuel tanker fires. In Part III the new design curves (developed as mathematical functions) were implemented into the OpenSees software framework to enable a seamless simulation from fire, to heat transfer and structural response.

▼

Sprayed Fire-Resistive Materials (SFRM) is a material family used for the passive fire protection of steel structural members. These materials can sustain damage when the underlying steel member is subjected to mechanical deformations, which can compromise their fire protection capability, and consequently affect the fire resistance of the structural member. The aim of the doctoral dissertation is the numerical assessment of the reduction in the fire resistance of steel elements with SFRM coatings that have sustained damage as a result of structural loading, and the quantification of the correlation of the reduction in the fire resistance with the imposed structural load and the corresponding damage in the coating.The damage of the SFRM coatings is studied numerically through mechanical analyses and heat transfer analyses in IPE and HEB SFRM protected beams. The first objective is the effective numerical simulation of the structural behavior and the induced damage in SFRM coatings. To this end, a numerical method is proposed, combining the smeared crack model with the discrete crack concept in a mesh splitting scheme, within the Finite Element Method, which can introduce geometric discontinuities (cracks) in the finite element mesh and create separate material sections that can independently detach from the steel member. The proposed method is validated against test data of corresponding tests of SFRM protected steel plate specimens and a steel column. The implementation of the proposed method in a series of parametric mechanical analyses, considering the section type, the SFRM thickness, the type and magnitude of the applied load and the presence of initial geometric imperfections, indicated that the damage pattern in the coating is a result of the combination of material cracking and interface failure between the two materials, and can be categorized in two damage states, depending on the level of the applied load.After the damage pattern in SFRM coating is established the IPE and HEB profiles under study are subjected to standard ISO-834 thermal loading, with and without the damage in the SFRM coating. Through numerical F.E.M. 3-D heat transfer transient analysis, the temperature distribution in the steel cross-section is obtained.Taking into account the non-uniform temperature distribution across the cross-section, the evolution of the bending moment resistance of the structural element is calculated for the duration of the applied thermal load. The reduced bending moment capacity is compared with the capacity of the beams with the intact coating, so that the reduction in the Fire Resistance of the member can be quantified. The reduction of the bending capacity is described through the calculation of appropriate reduction factors. The reduction of the fire resistance is also computed in the time domain.

У овом раду је анализирано је понашање појединачних немалтерисаних и малтерисаних бала сламе и немалтерисаних и малтерисаних зидова од бала сламе. Анализирана је могућност примене бала сламе за израду носећих зидова приземних објеката. На основу спроведеног експеримента утврђен је модул еластичности за немалтерисане бале сламе од око 400 kPa, а за малтерисане бале сламе од 1580 kPa. За бале сламе одређена је запреминска тежина од 1.18 kN/m3. Испитиване су и реолошке карактеристике зидова и дефинисани су модели понашања, као и величине тренутних и временских деформација. При испитивању на пожар једнострани малтерисани зид после два сата под дејством пламена није имао видних оштећења и нису биле битно промењене конструктивне карактеристике. Анализом доступне литературе дошло се до нивоа заштите од буке, као и нивоа топлотне заштите. Економска анализа показала је значајне финансијске погодности при градњи сламом. На основу спроведене експериментално-теоријске анализе доказано је да бале сламе задовољавају све потребне критеријуме, као и да се могу примењивати за израду носећих зидова у конструкцијама.

▼ Intumescent coating fire protection on steel structures is becoming widely popular in the UK and Europe. The current assessment for the fire protection performance method using the standard fire resistance tests is not accurate, owing to the reactive behaviour of intumescent coating at elevated temperature. Moreover, the available intumescent coating temperature assessment method provided in the Eurocode for structural steel at elevated temperature does not incorporate the steel beam's behaviour and/or assessment for partial protection and/or damaged protection. The research work presented provides additional information. on the assessment of partial and/or damaged intumescent coating at elevated temperature. In the scope of the investigation on the thermal conductivity of intumescent coating, it was found that the computed average thermal conductivity was marginally sensitive to the density and emissivity at elevated temperature. However, the thermal conductivity was found to be reasonably sensitive to the differences in initial dft's (dry film thicknesses). In this research, a numerical model was developed using ABAQUS to mimic actual indicative test scenarios to predict and establish the temperature distribution and the structural fire resistance of partial and/or damaged intumescent coating at elevated temperatures. Intumescent coating actively shields when the charring process occurs when the surface temperature reaches approximately 250°C to 350°C. Maximum deflection and deflection failure times for each damage scenario were analyzed by applying specified loading conditions. It was also found that the structural fire resistance failure mode of intumescent coating on protected steel beams was particularly sensitive to the applied boundary conditions. Careful selection of nodes in the element was necessary to avoid numerical instability and unexpected numerical error during analysis. An assessment of various numerical models subjected to a-standard fire with partially protected 1 mm intumescent coating was analysed using ABAQUS. An available unprotected test result was used as a benchmark. The outcome suggests that the fire resistances of the beams were found to be sensitive to the location of the partial and/or damage protection. The overall fire resistance behaviour of intumescent coating at elevated temperature was summarized in a 'typical deflection regression' curve. An extensive parametric analysis was performed on localized intumescent coating damage with various intumescent coating thicknesses between 0.5mm to 2.0mm. It was found that the average deflection was linear for the first 30 mins of exposure for all the variables, damage locations and intumescent thicknesses. It was concluded that a thicker layered intumescent coating may not be a better insulator or be compared to a much less thick intumescent coating at elevated temperature. The use of passive fire protection, however, does enhance the overall fire resistance of the steel beam, in contrast to a naked steel structure. The research work…

▼ Fire separations in a building (e.g. walls) are often constructed from combustible materials; those containing wood stud framing, mineral wool insulation, and gypsum board wallcoverings are commonplace in Canadian residential buildings. These construction assemblies degrade under fire exposure, a process involving chemical decomposition as well as physical damage. A fire separation's ability to resist the spread of fire is traditionally assessed by means of a fire resistance test, in which a construction assembly is exposed to an intense furnace fire under prescribed conditions. This method of assessment, while standardized and prescribed in the National Building Code of Canada, can be restrictive to the design process. In contrast, a performance-based approach, in which the adequacy of a fire separation is assessed on the basis of its real-world use, can lead to designs with improved safety, efficiency, and flexibility. Such a design approach requires a specific engineering toolset: models capable of predicting the thermal degradation of construction assemblies under specified fire conditions. Development of the next generation of thermal degradation models requires detailed study of the phenomena occurring at the large-scale, in the context of real fires rather than prescribed exposure conditions, and a controlled means by which to conduct this type of study. Also, a diverse set of experimental data is required for the validation of such models. The objective of the present body of work is to develop a novel large-scale experiment tailored specifically for the study of thermal degradation of construction assemblies in real fires, and to demonstrate the utility of the experimental procedure as applied to the detailed study of thermal degradation phenomena. A selection of relevant experimental techniques were identified, and a new apparatus and method of test were developed for this stated purpose. In this new experiment, one wall of a fire compartment was instrumented and monitored as it was subject to a realistic fire exposure. A novel method for measurement of incident heat flux to a large area in a fire compartment was developed, and used to characterize the conditions of the experiment for a wood crib fire. A series tests were conducted on fire resisting compartment partitions that are used in residential buildings in Canada. In the tests, thermal degradation phenomena were observed and assessed relative to temperatures measured in the degrading walls. The utility of this new approach in the experimental study of thermal degradation of construction assemblies subject to real fire exposures was demonstrated. Furthermore, a relevant set of experimental data was generated that may be used for validation of future models of thermal degradation and integrated fire analysis.

The studies presented in this thesis under the title "Thermal models for fire safety – calculation of flame spread on surfaces and heating of structures" consist of two parts: flame spread on combustible surfaces and calculation of heating of structures. This work consists of the development of thermal models for Fire Safety purposes. The main objective of the present thesis work is to produce new information for fire safety related to the development of models for flame spread on surfaces and to develop engineering calculation methods in heating of structures. In the context of Fire Safety, the word "fire" means accidental unwanted fires. The primary goal in Fire Safety is to protect life and property. The research field is relatively young and multi-disciplinary. The growth rate of a fire depends on how fast the flame will spread and involve more burning surfaces. In an enclosure, the burning rate is enhanced due to feedback effects but it is still the increasing area of the fire that affect the flame size. In fully developed fire, as in enclosures, the availablilty of air limits the rate of heat release. Fire growth rate and the rate of heat release depend highly on how rapidly the initialized fire propagates on surfaces. Thus, it is the flame spread that controls the rate of heat release in large or open spaces. This shows the importance of modeling flame spread, due to its direct impact on fire safety. This first part of the work discusses upward surface flame spread on a combustible solid surface. The flame spread is a process of a moving flame in the vicinity of a pyrolysing region on the surface which acts as a fuel source. The flame itself results from the combustion in the atmosphere of the pyrolysed gases leaving the surface. The oxygen and fuel concentrations together with the heat transfer phenomena between the flame and the solid phase affect strongly the process. Flame spread models of various levels of complexity are developed. A novel thermal pyrolysis upward flame spread model is also developed to predict the fire growth of combustible charring wall linings. Heat release rate in fires is of primary importance. When a structure is present, a part of the calorific energy dissipated in the fire is fed back to the structure via thermal radiation and convection with consequence of raising its temperature. As the performance of structures decrease with the increasing of temperature, knowledge of temperature distribution within the structure it is important to estimate the safe-escape time for occupants, safe-operational time for firemen and fire resistance. It is therefore essential to model heat transfer in structures. In the second part of the thesis heating of structures and temperature calculations in solids are addressed. Efficient engineering temperature calculation algorithms for various fire heated structures are developed.

▼ This thesis focuses on fire resistance of 19th century cast iron framed structures. Based on material property data obtained from a comprehensive literature review, upper and lower bound relationships of the thermal and mechanical properties of 19th century fireproof floor construction materials have been derived. Because these materials have large variability, a sensitivity analysis has been undertaken to investigate the most effective ways of representing such variability. The sensitivity analysis has indicated that the elevated mechanical properties of cast iron should be reliably quantified. The thermal expansion of cast iron can be taken as equal to that of steel as in EN1993-1-2. Variabilities in other material properties have modest effects on fire resistance of cast iron structures and can be safely modeled according the Eurocode material models for similar modern materials (using thermal properties of modern steel for cast iron, using thermal properties of modern concrete for the insulation materials of cast iron structures). In order to resolve some of the uncertainties in mechanical properties of cast iron at elevated temperatures, a total of 135 elevated temperature tests have been performed, including tension and compression tests, transient state and steady state tests, tests after cooling down and thermal expansion tests. These test results have been used to establish the elevated temperature stress-strain-temperature relationships in tension and compression. Afterwards, calculation methods are developed to calculate the bending resistance of cast iron beams and compression resistance of cast iron columns at elevated temperatures. For cast iron beams, a fibre model has been developed to calculate elevated temperature moment capacity of cast iron beams in jack arch construction, taking into consideration non-uniform temperature distributions in the cross-section. The fibre model divides the cross section into a large number of fine layers and for a given curvature and neutral axis position calculates the strain, the temperature, the stress and the force of each layer. It has been found that under historically applied load, the fire resistance of such beams can be 60 minutes or higher. The Monte Carlo simulation method has been used to take into account the variabilities of important mechanical properties of cast iron at elevated temperatures; Young’s modulus, 0.2% proof stress, ultimate strength, corresponding strain at ultimate strength and failure strain in tension and Young’s modulus, proportional limit and 0.2% proof stress in compression. This has enabled material safety factors of 1.50, 2.50, 4.50 and 5.50 to be proposed for target failure probabilities of 10-1, 10-2, 10-3 and 10-4 respectively. For cast iron columns, a finite element model, built using the commercial software ABAQUS, has been used to examine the effects of changing different design parameters (column slenderness, member imperfection, cross section imperfection, degree of axial restraint, load factor and load eccentricity) on fire…

▼ Composite slab flooring systems for steel-framed buildings consist of a profiled steel deck and a cast in-situ slab. The slab traditionally includes a layer of light gauge steel mesh reinforcement. This mesh is placed near the surface, which controls the early-age cracking caused by concrete drying and shrinkage. The steel mesh also performs a vital structural role at high temperatures. Structural fire tests and numerical investigations over the last 15 years have established that the mesh can provide enhanced fire resistance. A load-carrying mechanism occurs in fire with the mesh acting as a tensile catenary, spanning between perimeter supports. This structural mechanism is currently utilised regularly in the performance-based fire engineering design of steel-framed buildings. In a recent development, this mesh can be removed by using concrete with dispersed polymer fibre reinforcement to form the composite slab. The polymer-fibre-reinforced concrete (PFRC) is poured onto the deck as normal, and the fibres resist early crack development. For developers this technique has several advantages over traditional reinforcing mesh, such as lower steel costs, easier site operations and faster construction. However, to date the fire resistance of such slabs has been demonstrated only to a limited extent. Single element furnace tests with permissible deflection criteria have formed the basis for the fire design of such slabs. But these have not captured the full fire response of a structurally restrained fibre-reinforced slab in a continuous frame. The polymer fibres dispersed throughout the slab have a melting point of 160ºC, and it is unclear how they contribute to overall fire resistance. In particular, there has been no explanation of how such slabs interact with the structural perimeter to maintain robustness at high deflections. This project was designed to investigate the structural fire behaviour of restrained polymer-fibre-reinforced composite slabs. An experimental series of six slab experiments was designed to investigate the effects of fibre reinforcement and boundary restraint. A testing rig capable of recording the actions generated by the heat-affected slab was developed and constructed. Model-scale slab specimens were tested with different reinforcement and perimeter support conditions, to establish the contributions to fire resistance of the polymer fibres and applied structural restraint.

▼ Load-bearing cold-formed steel (CFS) wall systems are commonly constructed with CFS C-shape studs with one or two layers of fire-rated sheathing attached to both sides. In practice, perforations are placed in stud webs to accommodate the passage of utilities or installation of intermediate braces. These walls may fail by local buckling at the web perforations, combined with studs bending towards the furnace, as demonstrated by several full-scale fire tests. Current understanding of fire performance of such walls with web-perforated studs remains relatively limited, and the effect of web perforations on the fire resistance have not yet been accounted for in current design methods. Finite element analysis (FEA) using the software ABAQUS, an alternative to full-scale fire tests, was employed to investigate the heat transfer and structural responses of CFS walls. Three-dimensional heat transfer models were developed and validated with full-scale fire tests. Parametric studies demonstrate that for insulated CFS walls, web perforations induce a larger temperature gradient in perforated cross sections than in the solid ones along the stud length; however, for non-insulated CFS walls, the effect of web perforations on the temperature distributions in stud cross sections is negligible. Sequentially uncoupled 3D FE thermal-stress models were developed to evaluate the fire performance of load-bearing CFS walls with web-perforated studs. These walls were partially insulated, sheathed by double layers of MgO board or Type C gypsum board, and by mixed Type X and MgO board. Unlike in previous studies, temperature distributions incorporated into the structural model were obtained from heat transfer analysis so as to include the difference in temperature distributions caused by web perforations. Three models were developed: (1) a CFS wall stud model, as in previous studies. The predicted failure time is acceptable when compared with that of full-scale fire testing. (2) a CFS wall frame model. Stiffness and force interactions among the CFS wall studs were considered. The middle few studs of the wall frame may bear higher loads than that applied to a single stud, demonstrating that the single stud model may overestimate fire resistance. Thus, the stiffness and force interactions should be considered in the FEA to achieve better accuracy. (3) a CFS wall system model. Sheathing, attached to CFS wall framing, may enhance the load carrying capacity of walls. Such an increase in load carrying capacity is permitted and can be evaluated in the design of CFS walls at ambient temperature. However, the effect of using sheathing to brace to wall studs has not been investigated at elevated temperature. Modelling sheathing using shell element, in addition to the CFS wall frame, provides more realistic prediction of the structural response of full-scale fire tests than the above-mentioned two models. A simplified design method is extended for CFS web-perforated studs in walls, subjected to standard fire, based on effective width method as…
