▼ External confinement of concrete columns with fibre-reinforced polymer (FRP) sheets has been shown to lead to significant improvements on the axial compressive behaviour of these columns. This application of FRP composites is effective as a confinement material for concrete, in both the seismic retrofit of existing reinforced concrete columns and in the construction of concrete-filled FRP tubes (CFFTs) as earthquake-resistant columns in new construction. However, experimental studies on the axial compressive behaviour of FRP-confined concrete columns manufactured with high strength concrete (HSC) remain very limited. This thesis presents the results from a Ph.D. study at the University of Adelaide that was aimed at undertaking a comprehensive review on the axial compressive behaviour of monotonically-loaded circular FRP-confined HSC columns. The 10 journal articles developed as part of this thesis present the findings from experimental tests on a total of 282 FRP-concrete composite specimens. The effects of amount of confinement, concrete strength, confinement method, specimen size, fibre type, manufacturing method, fibre orientation, specimen end condition, specimen slenderness, concrete shrinkage, strain measurement method, FRP overlap and lateral prestress were investigated. The test specimens were manufactured with aramid FRP (AFRP), carbon FRP (CFRP) or high-modulus CFRP (HMCFRP) and their unconfined concrete strengths ranged from 34.0 to 119.3 MPa. Specimens were manufactured as either FRP-wrapped or concrete-filled FRP tubes (CFFTs), with all specimens cylindrical in shape and the majority 152 mm in diameter and 305 mm in height. The large quantity of the results presented in this thesis allows for a number of significant conclusions to be drawn. The experimental results presented in this thesis provide a performance comparison between FRP-confined normal-strength concrete (NSC) and the experimentally limited area of FRP-confined HSC. The results from this thesis indicate that, above a certain confinement threshold, FRP-confined HSC columns exhibit highly ductile behaviour. However, for the same normalised confinement pressures, axial performance of FRP-confined concrete reduces as concrete strength increases. The results also indicate that the behaviour of FRP-confined concrete is significantly influenced by the manufacturing method, with specimens manufactured through an automated filament winding technique exhibiting improved compressive behaviour over companion specimens manufactured through a manual wet layup technique. In addition to this, the influence of fibre type was examined with an improvement in compressive behaviour linked to an increase in fibre rupture strain. Further experimental testing on the influence of specimen size, confinement method and end condition found these parameters to have negligible effect for the range of parameters tested in this study. Experimental testing on specimens with inclined fibres revealed specimen performance is optimised when fibres are aligned in the hoop… Advisors/Committee Members: Ozbakkaloglu, Togay (advisor), Griffith, Michael Craig (advisor), School of Civil, Environmental and Mining Engineering (school).

▼ This dissertation presents the findings of an experimental and numerical research study that was conducted to study the behavior of corroded steel bridge piles that are repaired using fiber reinforced polymer (FRP)-confined grout-based systems. The objectives of this study were to, (i) quantify the remaining axial capacity of steel piles with different patterns of localized corrosion, and (ii) develop a rational approach for the design of FRP-confined grout-based systems for underwater repair of corroded steel H-piles. To achieve the first objective, a series of small-scale and full-scale piles with simulated corrosion patterns were tested under concentric compression loading. Thirteen small-scale steel wide flange columns and seven full-scale steel H-piles with simulated deterioration were tested under axial compression. Deterioration was simulated by milling the flanges and webs. The test results indicate that the degree of reduction of the thicknesses of the flanges and webs, presence of through-web corrosion, and length of the corroded region were the major parameters affecting the axial capacity of the corroded columns. Using existing design specifications, including the approach adopted by the American Institute of Steel Construction (AISC) and the American Association of State Highway and Transportation Officials (AASHTO) and those adopted by the American Iron and Steel Institute (AISI) (the effective width and direct strength methods), the remaining axial capacity of the tested piles was predicted and compared with the measured capacities. The findings indicate that among the methods investigated the effective width method resulted in the most accurate but still conservative estimate of the axial capacity. Subsequently, a rational approach was developed for the design of FRP-confined grout-based repair systems for corroded steel H-piles. Two groups of seven full-scale H-piles with different patterns of simulated corrosion were tested under concentric axial compression. Each group was repaired using a different commercially available FRP jacket system. The fabrication process was implemented underwater to simulate in-situ repairs. The test results indicate that the axial capacity of the repaired piles was successfully restored to the nominal capacity of the uncorroded piles. A complementary numerical study was conducted to further investigate the behavior of the repaired piles. The results of the numerical analysis showed that both the axial capacity and the failure mode were affected by changing the bond characteristics of the interface between the steel pile and the grout core of the repair system. The outcomes of the study provide a rational methodology for predicting the remaining capacity of corroded steel H-piles and for designing FRP-confined grout-based systems to retrofit corroded steel bridge piles.

▼ This dissertation presents the details of an experimental and numerical program that was conducted to evaluate the effectiveness of a new type of shape memory alloy (SMA)/fiber reinforced polymer (FRP) patch for repairing fatigue-sensitive steel elements. A nickel-titanium-niobium SMA was combined with carbon fiber reinforced polymer (CFRP) to develop a patching system to reinforce fatigue-sensitive steel elements. This thermally-activated system provides a more simple, practical and accessible method for prestressing composite patches than conventional prestressing approaches. Experimental results indicate that the composite increased the average fatigue life of fatigue sensitive elements by 15 and 26 times at stress ranges of 217 and 155 MPa, respectively. A digital image correlation (DIC) system was employed to study the interfacial debonding between the patch and substrate during fatigue loading. The influence of near-crack debonding on the strengthening effects was further studied using finite element (FE) methods. A linear elastic fracture mechanics (LEFM)-based numerical framework was established to perform a fatigue crack growth (FCG) analysis of steel elements that are reinforced with the SMA/FRP composite patches. The small crack propagation was taken into account using an equivalent initial flaw size (EIFS) method. The numerical framework was validated using the experimental results and the validated model was used to conduct a parametric study. The numerical study indicated two primary mechanisms by which the patches improved the fatigue lives of the repaired details: (i) activation of the SMA induced compressive stresses in the steel near the crack thereby increasing the critical crack length at which the element failed, and (ii) the CFRP provided a crack bridging effect which reduced the stress range in the steel locally near the crack thereby reducing the crack propagation rate. As a result, the synergistic effect between the SMA and FRP substantially extends the fatigue life of steel element. It was also found that the patch was more effective at increasing the fatigue lives of elements that were subjected to lower stress ranges. The research findings also indicated that early installation of the SMA/FRP patch results in much higher fatigue life improvement. However, installation of the patch at late stage of crack propagation, such as in an emergency repair can also significantly increase the fatigue life of cracked components providing an opportunity to mobilize a more permanent solution. Collectively, the research findings demonstrate that SMA/FRP patches are a promising new technology for repair of cracks in steel and other metallic structures.

▼ Well established analytical models and design guidelines are already available for analyzing and designing FRP strengthened structures under flexural and axial-confinement actions. However, the understanding of the behavior of such members under in-plane stress field remains a subject of on-going discussion among several researchers and practitioners. Several analytical models have been proposed to predict the gain and upgrade of shear capacity due to FRP strengthening, among which, most models resulted in large discrepancies and produced large scatter when compared to experimental database. This is due to the lack of accurate constitutive models for strengthened reinforced concrete (RC) with FRP (FRP-RC) members. An efficient method to study the overall response of an RC member is to identify the characteristic behavior and the contribution of each material constituting the structure, the behavior of that specific element can be predicted by taking into account the inherent characteristics and material laws of the constituents that leads to understanding the global shear response of the structure. As a first step of developing a shear model of FRP-RC elements, constitutive laws of each material component, namely concrete, steel reinforcement, and FRP sheets were studied in this research project through experimental and analytical investigations. Thirteen full-scale prismatic specimens and six full-scale panels were tested using the Universal Panel Tester (UPT) to study the stress-strain relationships of concrete, steel and FRP in tension as well as concrete in compression and the Poisson effect resulting from the biaxial loading. The results indicate that compared to the un-strengthened RC element, the presence of the externally bonded FRP material typically alters the main characteristics of the stress-strain relationships for each components in FRP-RC element. These newly developed material laws will be used to further develop a model to predict the behavior of FRP strengthened RC elements subjected to shear and torsion. The results from both experimental and analytical study in this research project will provide a promising contribution to the prediction of the behavior of FRP-RC members under shear that will ultimately improve the accuracy of the available design guidelines.

This master thesis contains a study on the implementation of Fibre Reinforced Polymers (FRP) onto a steel bascule bridge, with the aim of weight reduction. As a case study, the Amalia bridge near Waddinxveen (crossing the Gouwe channel) is used. Two alternative design propositions are presented. The thesis has been subdivided into several parts, which are introduced below. The first part consists of several expositions. It examines the built up of a movable bridge, the material FRP & its properties together with methods of connecting an FRP deck to steel girders and the rules & regulations required for bridge design in the Netherlands. The second part is the design study, which contains an overview of the original Amalia bridge and the designs created based on adaptions of the original. The designs have been made to have a lower total weight than the Amalia bridge. A lower bound approach has been used, not an optimisation. Thus, leaving room for improvement. Two alternatives are discussed: a hybrid and a non-hybrid solution. A hybrid solution is defined as a solution with the full interaction between the FRP-deck and steel girders: allowing for shear transfer between the two and enabling the deck to function as the top flange of the steel girders. A non-hybrid solution only allows for the transfer of vertical forces and limits the transfer of shear, resulting in the structural separation between the deck and the girders. The design study has led to a weight reduction for both the hybrid and non-hybrid solution of 24 and 16% respectively. It can be concluded that both alternatives clearly illustrate the potential of FRP in bridge design, given the objective to reduce weight. It should be noted that in the case of a hybrid solution, the temperature influences become significant. This requires close attention to the details for the connection between the deck and girders.

▼ La détérioration des infrastructures au Canada due à la corrosion des armatures est l'un des défis majeurs de l'industrie de la construction. Les progrès récents dans la technologie des polymères ont conduit au développement d'une nouvelle génération de barres d'armature à base de fibres renforcées de polymères (PRF), (en particulier les fibres de verre). Ces barres, résistant à la corrosion, ont montré un grand potentiel d'utilisation pour mieux protéger les infrastructures en béton armé contre les effets dévastateurs de la corrosion. Avec la publication du nouveau code S807-10 "Spécifications pour les polymères renforcés de fibres" et la production de barres en PRF de très haute qualité, celles-ci représentent une alternative réaliste et rentable par rapport à l'armature en acier pour les structures en béton soumises à de sévères conditions environnementales. La conception des éléments en béton armé de barres en PRF est généralement gouvernée par l'état de service plutôt que l'état ultime. Par conséquent, il est nécessaire d'analyser les performances en flexion et le comportement en service en termes de déflexion et de largeur de fissures des éléments en PRF sous charges de service et de vérifier que ces éléments rencontrent les limites des codes. Aussi, de récents développements dans l'industrie des PRF ont conduit à l'introduction des barres en PRF avec des configurations de surface et des propriétés mécaniques différentes. Ces développements sont susceptibles d'affecter leur performance d'adhérence et, par conséquent, la largeur des fissures dans les éléments en PRF. Cependant, les codes de conception et les guidelines de calcul fournissent une valeur unique pour le coefficient d'adhérence (k[indice inférieur b]) en tenant compte des configurations de surface et en négligeant le type de barre en PRF, le diamètre de la barre, et le type de béton et de sa résistance. En outre, le code canadien S807-10 "Spécifications pour les polymères renforcés de fibres" fournit une étape en classant les barres en PRF par rapport à leur module d'élasticité (E[indices inférieurs frp]). Ces classifications ont été divisées en trois classes : Classe I (E[indices inférieurs frp]<50 GPa), Classe II (50 GPa [plus petit ou égal] E[indices inférieurs frp]< 60 GPa) et Classe III (E[indices inférieurs frp] [plus grand ou égal] 60 GPa). Ce programme de recherche vise à étudier expérimentalement le comportement en flexion des éléments en béton en service armé avec différents paramètres sous charges statiques. Le programme expérimental est basé sous plusieurs paramètres, dont les différents ratios de renforcement, différents types de barres (différentes classes comme classifiées par le CAN/CSA S807-10), le diamètre et la surface de la barre, la configuration ainsi que la résistance du béton. De plus, les recommandations actuelles de design pour les valeurs de k[indice inférieur b] et la vérification de la dépendance des valeurs de k[indice inférieur b] sur le type de barres (verre ou carbone), le diamètre des barres et le type de béton et sa… Advisors/Committee Members: Benmokrane, Brahim (advisor).

▼ Extensive research has been conducted on strengthening of shear-critical reinforced concrete (RC) beams, particularly using fiber reinforced polymer (FRP) strengthening systems. This previous research has helped to better understand the behaviour of shear strengthening systems and has improved the performance of existing shear strengthening systems. However, there is still a potential to further improve upon the performance of existing shear strengthening systems. A cement-based composite system is an innovative strengthening system that has similar benefits (such as light weight, ease of installation and non-corroding) to FRP systems, but overcomes some of the draw backs (such as poor compatibility with concrete substrate, lack of vapour permeability and fire resistance) of using epoxy as bonding agent in FRP systems. A cement-based composite replaces the epoxy with cementitious mortar and the fiber sheets with fabric or grids. The current study presents the results of an experimental study conducted to investigate the effectiveness of cement-based composite systems in comparison to an existing epoxy-based system (carbon fiber reinforced polymer, CFRP) to strengthen shear-critical RC beams. Two types of cement-based systems were investigated in this study: carbon fiber reinforced polymer (CFRP) grid embedded in mortar (CGM) and carbon fabric reinforced cementitious mortar (CFRCM). The experimental study consisted of two phases. Phase I focused on flexural testing of seven medium-scale shear-critical reinforced concrete (RC) beams. The objective of this phase was to evaluate the potential of FRCM shear strengthening. The test variables included the type of FRCM (carbon FRCM or CFRCM and glass FRCM or GFRCM) and the strengthening scheme (side bonded vs. U-wrapped). Phase II was designed based on results of Phase I study, and it consisted of flexural testing of twenty (20) large-scale shear-critical RC beams strengthened with cement-based systems. The objective of this phase was to evaluate the effectiveness of the two types of cement-based strengthening systems in comparison to the existing epoxy-based FRP system. The test variables included: the shear span to depth ratio (slender and deep beams), amount of internal transverse steel reinforcement and type of strengthening system (CFRCM, CGM and CFRP). The results showed that the cement-based systems (CFRP grid in mortar and CFRCM) performed better compared to the epoxy-based system (CFRP sheet) in terms of the increase in shear capacity relative to the ultimate strength of the strengthening systems. The results also showed that the bond of cement–based system with the concrete substrate was sufficient that u-wrapping may not be required; the studied side-bonded systems did not exhibit signs of premature debonding. This is in contrast to most FRP fabric strengthening systems were u-wrapping is required for adequate bond. In addition, cement-based systems exhibited a better ability to control diagonal (shear) crack widths compared to the epoxy-based system…

I dagsläget är de flesta broar i Sverige tillverkade med betong eller stål. Dessa broar är många gånger förknippade med stora kostnader som ofta beror på underhåll och reparation. FRP, som står för Fiber Reinforced Polymer, är ett relativt nytt material i bärande stommar men är ett väl etablerat material i förstärkningssammanhang. I Europa och i synnerhet Nederländerna finns det flertal broar byggda i FRP. Men på grund av brist på normer och regelverk att luta sig emot sker det sällan någon form av brokonstruktion med FRP i Sverige. Detta examensarbete syftar till att undersöka befintliga normer och studera hur materialet FRP används vid förstärkning och konstruktion av broar. Vidare syftar även arbetet till att undersöka egenskaperna hos FRP som byggmaterial och jämföra det med konventionella material som stål och betong. FRP, också benämnd fiberkomposit, är ett kompositmaterial som kan sammanställas på flera olika sätt. Genom olika material som kombineras och olika tillverkningsprocesser som används kan man på så sätt ge individuell utformning till materialet för dess användning. Fördelarna med FRP är många, men i allmänhet har det god styrka, god beständighet samtidigt som det har en låg vikt. Detta resulterar i att inom brokonstruktion så ger det strukturen en minskad egenvikt, vilket i sin tur underlättar en mängd olika saker. Detta arbete visar på att FRP-material har fördelaktiga egenskaper och kan i vissa situationer vara mer gynnsamt att använda än stål eller betong. Dock som tidigare påpekat saknas det specifika Eurokoder för detta material. Däremot är vi säkra på att introduktionen av en ny Eurokod samt med uppmuntran från myndigheter kommer användningen av FRP inom brokonstruktion utan tvekan öka.

At present, most bridges in Sweden are made with concrete or steel. These bridges are often associated with high costs, which often depend on maintenance and repair. FRP, which stands for Fiber Reinforced Polymer, is a relatively new material in load-bearing structures but is a well- established material in the context of reinforcement. In Europe and in particular the Netherlands, there are several bridges built in FRP. But due to a lack of norms and regulations to lean against, there is rarely any kind of FRP bridge construction in Sweden. The aim of this thesis is to examine existing norms and study how the material FRP is used in the reinforcement and construction of bridges. Furthermore, this thesis also aims to investigate the properties of FRP as building material and compare it with conventional materials such as steel and concrete. FRP, also called fiber-composite, is a composite material that can be assembled in several different ways. Through various materials that are combined and different manufacturing processes used, one can thus provide individual designs for the material. The benefits of FRP are many, but generally it has good strength, good durability while having a low weight. This results in that within bridge construction, it gives the structure a reduced self-weight, which in…

▼ Aging of civil infrastructures is one of the major problems faced by the engineering industry today, with the concrete structures cracking and the steel reinforcement corroding due to exposure to deicing chemicals, resulting in shorter service life. An alternative to the degrading infrastructures made of concrete and steel is the use of Fiber Reinforced Polymer (FRP) composites, which are noncorrosive. Use of FRP as structural components such as bridge decks and retrofitting jackets can solve the problem of aging with enhanced durability in future constructions. But, proper installation of newer material in structurally important infrastructure requires a reliable method of evaluation or testing. Nondestructive Testing (NDT) or Evaluation (NDE) is a method that can detect the anomalies in the FRP structures keeping the physical properties of the structure intact. Infrared Thermography (IRT) and Digital Tap Testing (DTT) are two extensively used NDT techniques for inspection of infrastructures, because of their portability and easy-to-handle features. This problem report discusses the advanced and conventional IRT and DTT methods to detect subsurface defects in FRP composite bridge components and FRP rehabilitated concrete bridge. Advanced IRT offers high-end infrared camera and robust digital image processing abilities to locate sub-surface defects in the structures, which, in some cases, conventional IRT fails to do. In addition, this report also includes IRT based tests using a low-cost halogen lamp heater, which is compared to the heating capability of VoyageIR Pro (advanced IRT equipment). Also, Digital Tap Hammer was used for rapid evaluation of the defects in the structural members, which provides a scientific alternative to the traditional coin tap method. The extent of applicability of DTT method compared to IRT was studied using several FRP specimens in the laboratory. DTT was limited to defects at lower depth, such as debonds in thin FRP wraps and could not detect delaminations in thick FRP members. The methods were also used in field testing of concrete box beams rehabilitated with carbon FRP fabrics. The field testing enabled the detection of debonds which helped in their immediate repair.

▼ Nondestructive Evaluation of Concrete Bridge Columns Rehabilitated With Fiber Reinforced Polymers Using Digital Tap Hammer and Infrared Thermography Andrew Wheeler In 2017, the American Society of Civil Engineers (ASCE) gave bridges in the U.S. a C+ rating. Almost four out of every ten bridges are 50 years or older. In 2016, there were on average 188 million trips across a structural deficient bridge each day. With such a large number of bridges needing replaced or repaired, transportation officials are utilizing various bridge rehabilitation techniques to provide a cost effective solution to such a widespread problem. One rehabilitation technique involves the application of Fiber Reinforced Polymer (FRP) composite wraps to strengthen various bridge components. The initial and in-service, evaluation and acceptance of such FRP systems are crucial to their overall success and serviceability. Previously, several traditional methods such as visual inspection and coin tap testing of FRP composites were accepted as common practice for inspecting the quality of material and structural components. This type of evaluation was very subjective and dependent on the inspector's level of experience. More recently, nondestructive testing (NDT) techniques can identify internal or external defects without affecting the form, or function of a structure. Digital Tap Hammer testing and Infrared Thermography (IRT) are two commonly used NDT techniques for field evaluation of civil infrastructure, because these techniques are user friendly and highly mobile. This problem report reviews the recent advances on the applications of digital tap hammer testing and infrared thermography at identifying defects in various elements of infrastructure and FRP composite wraps applied to bridge columns in southern West Virginia. Additionally, this report includes information on process of repairing dilapidated reinforced concrete columns in preparation for the installation of a FRP system. All of this will serve as a demonstration of how crucial non-destructive evaluation (NDE) is to the success of FRP bridge rehabilitation. Furthermore, the conclusions indicate a need for NDE to ensure quality control of field rehabilitation projects. Advisors/Committee Members: Udaya B. Halabe, Hota V.S. GangaRao, Hema J. Siriwardane.

▼ Since the 1920s, a significant research effort has been dedicated to the understanding of the improved compressive behavior of concrete under lateral confinement. Upon the introduction of fiber-reinforced polymer (FRP) composites to the construction industry, the use of FRP as confinement material has received much attention. To that end, a great number of studies have been conducted in the past two decades on the axial compressive behavior of unconfined, actively confined and FRP-confined concretes, resulting in the development of over 110 stress-strain models. These models are classified into four broad categories, namely design-oriented, analysis-oriented, evolutionary algorithm, and finite element models. In the present study, existing models in each category were carefully reviewed and assessed using comprehensive experimental test databases assembled through an extensive review of the literature. The databases cover more than 7000 test results of unconfined, actively confined, and FRP-confined concrete specimens from 500 studies. A close examination of the assessment results has led to a number of important findings on factors influencing the performances of existing models. For each model category possible areas for further improvement were identified and new models were proposed. First, an empirical model in simple closed-form expressions that are suitable for engineering design purpose was developed using the database of FRP-confined concrete. The distinct feature of this design-oriented model includes its applicability to normal- and high-strength concretes with cross-sections ranging from circular to rectangular. The model also considers the observed dependency of the hoop rupture stain of the confining jacket on the material properties of the concrete and FRP. In addition, a novel concept, referred to as the confinement stiffness threshold condition, was incorporated into this model to allow for an accurate prediction of post-peak strain softening behavior of FRP-confined concrete. Following this, using the combined database, a unified analysis-oriented model that is capable of predicting the complete stress-strain and dilation behaviors of unconfined, actively confined, and FRP-confined concretes was developed. It was found that, at a given axial strain, lateral strains of actively confined and FRP-confined concretes of the same concrete strength correspond when they are subjected to the same lateral confining pressure. However, under the same condition, concrete confined by FRP exhibits a lower strength enhancement compared to that seen in companion actively confined concrete. On the basis of this observation, a novel approach that incorporates the confining pressure gradient between the two confinement systems was established and a unified stress-strain model was developed. Other distinct features of this highly versatile model are its applicability to concretes ranging from light- to normal-weight and low- to high-strength. In addition, it is also applicable to specimens with various sizes and… Advisors/Committee Members: Ozbakkaloglu, Togay (advisor), Ng, Alex Ching-Tai (advisor), School of Civil, Environmental and Mining Engineering (school).

▼ Every year in the US and other cold-climate countries considerable amount of money is spent to restore structural damages in conventional bridges resulting from (or “caused by”) salt corrosion in bridge expansion joints. Frequent usage of deicing salt in conventional bridges with expansion joints results in corrosion and other damages to the expansion joints, steel girders, stiffeners, concrete rebar, and any structural steel members in the abutments. The best way to prevent these damages is to eliminate the expansion joints at the abutment and elsewhere and make the entire bridge abutment and deck a continuous monolithic structural system. This type of bridge is called Integral Abutment Bridge which is now widely used in the US and other cold-climate countries. In order to provide lateral flexibility, the entire abutment is constructed on piles. Piles used in integral abutments should have enough capacity in the perpendicular direction to support the vertical forces. In addition, piles should be able to withstand corrosive environments near the surface of the ground and maintain their performance during the lifespan of the bridge. Fiber Reinforced Polymer (FRP) piles are a new type of pile that can not only accommodate large displacements, but can also resist corrosion significantly better than traditional steel or concrete piles. The use of FRP piles extends the life of the pile which in turn extends the life of the bridge. This dissertation studies FRP piles with elliptical shapes. The elliptical shapes can simultaneously provide flexibility and stiffness in two perpendicular axes. The elliptical shapes can be made using the filament winding method which is a less expensive method of manufacturing compared to the pultrusion or other manufacturing methods. In this dissertation a new way is introduced to construct the desired elliptical shapes with the filament winding method. Pile specifications such as dimensions, number of layers, fiber orientation angles, material, and soil stiffness are defined as parameters and the effects of each parameter on the pile stresses and pile failure have been studied. The ANSYS software has been used to model the composite materials. More than 14,000 nonlinear finite element pile models have been created, each slightly different from the others. The outputs of analyses have been used to draw curves. Optimum values of the parameters have been defined using generated curves. The best approaches to find optimum shape, angle of fibers and types of composite material have been discussed. Advisors/Committee Members: Amde, Amde M. (advisor).

▼ Carbon fiber reinforced polymer (CFRP) reinforcement has been studied as an alternative to steel reinforcement due to steel's high susceptibility to corrosion in bridge girders. The use of deicing salts on roads during extreme cold is the primary cause of the corrosive environment due to salt percolation through cracks. This research manifests the flexural behavior of carbon fiber polymer reinforced beams in prestressed and non-prestressed conditions as well as the variation of the behavior from conventional steel reinforced beams including the design procedure of a prestressed CFRP box section beam through a case study.Unlike steel, CFRP has different stress versus strain relationship - linear without a definite yield point. A review of literature is done regarding the history, properties, applications, and researches in this field. A comparative study is done between the behavior of CFRP reinforced beams using previously tested rectangular and decked bulb T-beams. The study also focuses on the field of application, guidelines, and provisions in different parts of the world, design procedure, characteristics and weaknesses of the material, handling of CFRP in the field, and its design.The application of CFRP as the main reinforcement is scarce because of its brittleness and limited research. However, the strength and lightness make this material ideal for use in the construction industry. It is important that these beams have adequate ductility to prevent sudden failure. Ductility of similar types of beams with conventional and CFRP materials are studied and compared through deformability index. Several methods of calculating ductility are discussed and an ACI method is selected to find the ductility of each beam and a comparative study is done. The behavior of prestressed CFRP tendon is examined when it is used as an alternative to the conventional steel tendon through a case study relating different provisions of code through the design of a prestressed CFRP box section beam over the Ottawa river.

▼ Corrosion induced deterioration is one of the main reason for repair and rehabilitation programs in conventional steel reinforced concrete bridge decks. Of all bridges in the United States, over 50 percent are constructed of conventional reinforced or prestressed concrete (NACE, 2013), where one in three bridges are considered structurally deficient or functionally obsolete due to corrosion of the steel reinforcement. According to NACE International (2013) the annual cost of corrosion-related maintenance for highway bridges in the U.S. is estimated at $13.6 billion. Over the past couple of decades, fiber reinforced polymer (FRP) bars have been noted by researchers and engineers as a corrosion-resistant alternative for either conventional reinforcing steel or prestressing strands. High strength-to-weight ratio, corrosion resistance, ease in placement of the bars and accelerated implementation due to light weight are the special characteristics that make these bars an appealing alternative. Up to this end, extensive research has been conducted on the structural performance of FRP reinforced concrete beams and slabs; however, less attention has been paid to FRP reinforced concrete bridge girders in composite action with the bridge deck. Accounting for the effect of composite action between the bridge girder and deck can significantly impact the structural performance of the girder including the load and deformation capacities as well as the failure mode. Therefore, separate tests of the FRP concrete beams and slabs may not be sufficient to study the structural behavior and to provide design guidelines for engineers. This thesis presents the experimental and analytical investigations on structural performance of a full-scale AASHTO I-girder Type I, reinforced and prestressed with aramid fiber reinforced polymer (AFRP) bars, where the bridge girder is composite with the deck. The major objectives of this research were to develop a reliable prestressing anchorage system, examine the constructability of the full-scale specimen, study the load and deformation capacities, determine whether or not the design criteria per AASHTO LRFD were met, and improve the performance of the specimen by adjusting the prestressing layout. The specimen was constructed at a prestressing plant in San Marcos, Texas and tested at the High Bay Structural and Material Testing Laboratory on the campus of Texas A&M University. The cross-section of the bridge girder was composed of self-consolidating concrete with a total of 24 prestressed and 8 non-prestressed AFRP bars. The bridge deck consisted of a 203 mm (8 in.) conventional steel reinforced concrete slab. A flexure test was conducted to determine the moment-curvature relationship, flexure load capacity, and failure mode. The test was conducted as a simply supported, four point bending test in order to create a region of constant moment at the center of the beam. Two shear tests were conducted to determine the shear capacity, failure mode, maximum strain in the web, and moment-curvature… Advisors/Committee Members: Hurlebaus, Stefan (advisor), Mander, John B (committee member), Muliana, Anastasia H (committee member).

▼ Several investigations have revealed that many aging civil engineering structures such as highway bridges are structurally deficient and need repairs and/or retrofitting. Among various solutions, fiber reinforce polymer (FRP) composites have shown a promising solution and have been increasingly used in rehabilitation and strengthening of reinforced concrete (RC) structures. Although, researchers have devoted a tremendous effort on studies related to FRP shear strengthening of RC structures, the state of knowledge shows that the problem is not fully resolved and there are still controversies in the prediction of shear behavior in the presence of FRP. To predict the increase in shear capacity due to FRP strengthening, several analytical models have been proposed. However, when these models are compared using existing experimental database, they show inconsistencies and large scatter in the prediction. This is due in part to the high level of complexity associated with the shear behavior, but more importantly due to the lack of rational constitutive models for FRP shear strengthened elements. This research study aims at establishing the shear constitutive behavior of externally bonded FRP strengthened RC elements subjected to pure shear through experimental investigations and development of associated analytical and finite element models. In order to evaluate such behavior, at the first part of the research, a series of full-scale FRP strengthened RC panels were constructed and tested under pure shear stress field using the University of Houston’s state of the art panel tester. It was found that application of FRP sheets increased the shear capacity of RC panels. Also, the shear behavior of FRP strengthened RC members is influenced mainly by the FRP stiffness, wrapping scheme, and the internal shear reinforcement. Based on the test results, the Softened Membrane Model (SMM), which was developed for reinforced concrete, was modified and extended for application to FRP strengthened RC members. The second part of this research involved the development of a computer program for analysis of FRP strengthened RC structures. The constitutive laws of FRP strengthened RC members, developed through previous research at UH, have been implemented into the finite element frame work OpenSees to predict the behavior of FRP strengthened RC panels and beams under monotonic loading. The analytical model was tested and validated using existing experimental data. Furthermore, to investigate the serviceability conditions in FRP strengthened RC structures, the crack characteristics of a series of full-scale tensile tests of FRP strengthened RC prisms and test panels have been monitored by using a digital image correlation system. The experimental results were used to calibrate a newly developed equation to calculate crack spacing and crack width in RC elements externally strengthened with FRP.

Corrosion of steel in reinforced concrete structures is one of the biggest challenges faced by the civil construction industry today. In reinforced concrete structures, corrosion of steel reinforcement due to harsh environmental conditions considerably reduces the durability and life span of these structures. To overcome this corrosion problem, many new techniques have been tried and found to be either expensive or ineffective. Fiber Reinforced Polymer (FRP) materials in the form of solid bars has been successfully tried as a substitute for steel reinforcement in concrete structures. Considerable research has been carried out to study the flexural and shear behaviour of FRP reinforced slender concrete beams. However, very little effort has been taken to study the behaviour of Reinforced Concrete (RC) deep beams reinforced with FRP rebars. This work is an attempt to study the shear behaviour of RC deep beams reinforced with Glass Fiber Reinforced Polymer (GFRP) web reinforcement. The thirteen deep beams were cast with and without GFRP web reinforcement and were tested in this work. The testing was done in two stages - in the first stage, i.e. in Series-I, nine deep beams were tested with a shear span to effective depth ratio of 0.72 and the results showed a substantial increase in the ultimate shear load carrying capacity for deep beams reinforced with GFRP web reinforcement when compared to those without web reinforcement. Considering this significant increase, four more deep beams were cast in the second stage i.e. Series-II and were tested with a shear span to effective depth ratio of 1.08. Finally, after analysis of the experimental results, a design equation was formulated to predict the shear carrying capacity of GFRP web reinforced deep beams. The results obtained by using this equation were found to be acceptable and so, this equation may be adopted for predicting the shear load capacity of deep beams reinforced with GFRP web reinforcement and loaded within a small shear span to depth ratio.

▼ The use of composite materials (Fiber Reinforced Polymers - FRP) as internal and strengthening reinforcement in concrete structural members is becoming increasingly apparent. The ageing of the materials, the poorly detailed concrete members of the existing old Reinforced Concrete (RC) structures designed prior to 1970, the exposure of extremely important (RC) structures (e.g. bridges, highways etc.) in high corrosive environment owing to climate conditions or chemicals and the design requirements of modern seismic codes have led since several years the scientific community to investigate alternative methods of reinforcing and strengthening of the structural elements. In some cases, the use of FRP materials seem to be more advantageous than the use of the conventional steel reinforcement.The present research focuses on the investigation of innovative materials as main internal reinforcement or strengthening reinforcement of RC members with shear problems under monotonic and cyclic loading. The main axis is the interpretation and understanding the parameters that affect and determine the overall behaviour and failure mechanisms of these elements. For this purpose, an extensive experimental program was carried out which was divided into three parts.The first part concerns the experimental and analytical investigation of the use of Carbon FPR bars (C-FRP bars) as the main longitudinal reinforcement of structural RC members. In comparison with other commercially available FRP bars with lower cost such as FRP of glass fibers (G-FRP bars) C-FRP bars exhibit higher tensile strength and modulus of elasticity and an excellent corrosive resistance in harsh and aggressive environments (Fib bulletin 40 2007, ACI 440.1R-15 2015). In the first phase, seven (7) slender RC beams with rectangular cross-section were constructed and tested under 4-point monotonic loading with constantly increasing deformation: two (2) beams are reinforced with conventional steel tensional bars as the reference specimens and five (5) with C-FRP bars. Two types of C-FRP bars with different nominal diameter were chosen (df = 5.5 mm and df = 10 mm). The examined specimens were designed according to the design guidelines of ACI 440.1R-15 (2015). Special attention has been given on the bond conditions of the anchorage lengths of the tensile C-FRP bars. In this direction, an additional enhanced anchorage configuration along the straight anchorage length of the tensional FRP bars consisted of a continuous mild steel spiral with circular shape was also investigated. According to the experimental observations useful findings have been conducted regarding the overall response and the failure mechanism of these structural members.Concerning the analytical part of this research a feasible and easy-to-apply numerical approach for the evaluation of the flexural and the shear strength of slender concrete beams reinforced with longitudinal FRP bars, with or without steel stirrups, and consequently for the prediction of the expected failure mode is proposed. A unified…
