Abstract:
Glass fiber reinforced polymer (GFRP) composites have been frequently used in engineering applications in recent years. GFRP composites produced by using glass fiber and epoxy resin have significant advantages such as high strength, lightness, and resistance against corrosion. However, GFRP composites exhibit a more brittle behavior than steel bars. This study aims to investigate both the experimental and numerical bending behavior of slabs with GFRP bars, steel bars, and polypropylene fiber. Within the scope of experimental studies, 5 slabs were built. Two slabs called SS-1 and SS-2 have only steel bars. Two slabs called GFRPS-1 and GFRPS-2 have only GFRP composite bars. A slab called GFRPS-F has both GFRP composite bars and polypropylene fibers. Polypropylene fibers are added to fresh concrete to improve the slab’s ductility. Three-point bending tests have been carried out on the slabs. All slabs are subjected to monotonic increasing distributed loading until collapse. As a result of tests, GFRPS slabs have carried %53 higher load than SS slabs. However, the SS slabs have exhibited a more ductile behavior compared to the GFRPS slabs. GFRPS slabs have more and larger crack width than other slabs. The addition of 5% polypropylene fiber by volume to concrete has a significant contributed to ductility and tensile behavior of slab. The average displacement value of GFRPS-F slab is 22.3% larger than GFRPS slab. GFRPS-F slab has better energy consumption capacity than other slabs. The energy consumption capacity of GFRPS-F slab is 1.34 and 1.38 times that of SS and GFRPS slabs, respectively. The number of cracks in GFRPS-F slab is fewer than GFRPS slabs. The fibers have contributed to the serviceability of the GFRPS slabs by limiting the displacement and the crack width. GFRPS-F exhibits elastoplastic behavior and almost returns to its first position when the loading is stopped. In addition, experimental results are verified with numerical results obtained by using Abaqus software. Finally, it is concluded that GFRP composite bars can be safely used in field concretes, concrete roads, prefabricated panel walls, and slabs.

Abstract:
A composite slab comprised of self-compacting rubber lightweight aggregate concrete (SCRLC) and profiled steel sheeting is a new type of structural element with a series of superior properties. This paper presents an experimental research and finite element analysis (FEA) of the flexural behavior of composite slabs consisting of SCRLC to develop a new floor system. Four composite slabs specimens with different shear spans (450 mm and 800 mm) and SCRLC (0% and 30% in rubber particles substitution ratio) are prepared, and the flexural properties including failure modes, deflection at mid-span, profiled steel sheeting, and concrete surface stain at mid-span and end slippage are investigated by four-point bending tests. The experimental results indicate that applying SCRLC30 in composites slabs will improve the anti-cracking ability under the loading of composite slabs compared with composite slabs consisting of self-compacting lightweight aggregate concrete (SCLC). FEM on the flexural properties of SCRLC composites slabs show that the yield load, ultimate load, and deflection corresponding to the yield load and the ultimate load of composite slabs drop as the rubber particles content increases in SCRLC. The variation of SCRLC strength has less impact on the flexural bearing capacity of corresponding composite slabs. Based on the traditional calculated method of the ultimate bending moment of normal concrete (NC) composite slabs, a modified calculated method for the ultimate bending moment of SCRLC composite slabs is proposed.

Abstract:
The aim of this research is to investigate experimentally the effect of adding shear connectors to the composite deck slabs which have various geometries of steel sheeting. The behavior and resistance of composite slab is basically depending on the development of longitudinal shear resistance. In this study six specimens of composite deck slabs which have different types of geometries of steel sheets (trapezoidal, triangle and T-shapes) with dimensions (1850mm x 500mm x 110mm) were casted and tested under four-point load in presence and absence of shear connectors in order to evaluate the behavior and longitudinal shear resistance of composite slabs. The results show that the adding shear connectors to composite slabs with trapezoidal shape and triangle shape act to increase ultimate load capacity by 22.2% and 17.8% respectively as compared with composite slabs without shear connectors while effect of adding shear connectors to the composite slab with T-shape was very little or can be neglected. As well as the adding shear connectors to composite slabs with trapezoidal shape and triangle shape act to decreasing the deflection as compared with the same load also act to enhance the general performance of slabs

Abstract:
Steel reinforced concrete is generally used in houses structure elements. However bamboo strength properties similarly to the wood, make it an alternative concrete composite material. Load test were performed in two kinds of bamboo guadua concrete reinforced composite slabs. During the tests the slabs functioned as domestic roofing-flooring in standing houses, the slab systems tested were bamboo stem covered slab and stem free slab. Two different tests were designed to measure the deflection in the middle of the composite slab and along a single bamboo stem. In three different slab sizes and after replications, no deflection under the applied load was recorded. Therefore, bamboo composite slabs without steel reinforcing seem likely to be used in long lasting houses for middle and high class dwellings in Colombia.

Abstract:
The pre-stressed concrete composite slab, which combines the advantages of cast-in-place slabs and precast slabs, has promising development prospects. In the paper, according to structural integrity, bond performance, sound insulation, thermal preservation and construction techniques, four categories composite slab, such as the composite slab with flat bottom panel (including the composite slab with bar truss reinforced precast concrete bottom panel), the concrete composite slab with precast ribbed panel, the composite slab with hollow bottom panel and the composite slab with sandwich bottom panel are studied. The composite slab with flat bottom panel has poor structural integrity, and its bond performance and crack resistance of edge joint details need to be improved; the composite slab with bar truss reinforced precast concrete bottom panel has enough bond force, but its storage and transportation are inconvenient; the concrete composite slab with precast ribbed panel has good structural integrity and convenient construction procedure; the composite slab with hollow bottom panel and the composite slab with sandwich bottom panel have functions of sound insulation and thermal preservation, however they are inadequacy to resist bending moment and have complex construction procedure. The concrete composite slab with precast ribbed panel is provided with good mechanical behavior, economy and practicability, and is worth further researching and promoting.

Abstract:
This study investigates the possibility of inducing damage diagnosis capabilities in carbon fiber reinforced polymer composite slabs using custom-built integrated sensors and conventional, affordable equipment. The concept utilizes magnetoelastic strips integrated via 3D printing procedures in composite slabs. Under external mechanical loading, the strip magnetization changes due to the magnetoelastic phenomenon. Accordingly, electrical signals may be passively induced in conventional reception coil circuits placed at a distance from the slab. Since these signals quantify the vibrating slab’s response, which is affected by the slab’s structural integrity, damage may be detected when specific signal characteristics change. Two main issues are examined, namely the ability of receiving meaningful (with respect to noise) electrical signals from the built-in strips despite their contact-less passive reception, and the potential of diagnosing damage using such signals. Hence, slabs of various sizes and levels of structural damage (notches) have been vibrated at different frequencies and amplitudes. Treating the experimental data from integrated strips by applying the proposed processing framework allows for calculating eigenfrequencies sensitive to occurring damage (and its severity), as verified by finite element models of the vibrating slabs. Accordingly, damage may be detected and evaluated via the currently proposed experimental testing and analysis framework.

Abstract:
Composite construction is widely used worldwide and is undergoing significant technological development. New Zealand is part of this development, with new beam options incorporating multiple unstiffened web openings and new deck profiles supported by extensive testing. However, one area where relatively little research has been undertaken is in the interaction of the composite slab with the seismic resisting system under lateral loading. In order to provide important new information in this area, a series of full scale beam-column-joint-slab subassemblies were tested at the University of Canterbury. Specimens tested had moment end plate connections and different combinations of deck tray direction, and isolation of the slab from the column. An additional test uses a sliding-hinge type connection to assess the effect of the floor slab in this type of low damage connection. In these tests the lateral capacity of the seismic resisting system was increased by up to 25% due to the presence of the slab in contact with the column. The increase in capacity is 10% greater for decking running in longitudinal direction than in the transverse direction as a result of a more substantial full depth slab bearing on the column. The floor slabs of the subassemblies with the slab cast against the column all showed a higher level of damage than for those with the isolated column and the post ultimate strength degradation of the subassemblies without special detailing was significant. The subassembly with a section of full depth slab surrounding the column also exhibited a higher capacity but with an improved post ultimate strength degradation. All moment end plate subassemblies sustained drifts of up to 5% without significant strength loss. The sliding hinge joint showed little signs of damage under testing to 5% drift. Some inelastic deformation of the connection and beams was noted above 5% drift. Results from both testing and numerical modelling have shown that the current methods used to design these systems are conservative but within 15% of the values observed. Further testing and modelling will be necessary before any meaningful changes can be made to the way in which these systems are designed. Recommendations have been made regarding the placements of shear studs in plastic hinge zones and the provision of slab isolation around beam-column connections.

Abstract:
The concrete-steel composite slabs show a complex structural characterization due to the different behaviours at the two materials. The materials are exposed to different deformations, large deflections and complex stresses with still a limited understanding of their micromechanics. Hence, current building codes rely on expensive and tedious laboratory tests that characterize the composite slab failure and the ultimate resistance. The Finite Element (FE) numerical simulations were introduced more than 25 years ago in composite slab studies as a mechanism to validate new design methods and also as an alternative to reduce laboratory tests requirements. However, the simulations historically observed a significant number of simplifications such as reduced scale models or simplified geometries. This dissertation introduces initially a novel modeling and simulation methodology that enables new insights in the steel deck and concrete slab response for bending. Distinct full-scale finite element models were generated for four commercial steel deck profiles to simulate the laboratory tests. An intense and systematic optimization process was carried out as the computational costs and the simulation files size associated with the initial FE models were significant. The three-dimensional composite models detailed embossment depth and slope, steel thickness, or tilting angle, among several others. Common limitations and simplifications related to steel-concrete contact, adhesion, and cohesion factors in previous research efforts were addressed. Newton-Raphson was the simulation method and enabled the consideration of geometrical and materials nonlinearities. The proposed methodology was validated by comparison of the results from the bending simulations with the actual maximum loads, midspan deflection and end slip values obtained from laboratory bending tests. Based on the robustness of the bending simulations, parametric and boundary conditions analyses were performed through pull-out simulations. Micromechanics phenomena that could not be observed during laboratory tests were investigated at the full-scale bending simulations. First, the neutral axes and vertical disconnection representations for the steel deck and concrete slab were characterized and subsequently they proved the existence of partial connection between the materials. Second, a new normal vertical tension parameter sshear was introduced to describe the vertical stresses at the steel deck and the concrete slab. Third, the longitudinal shear strength Zu was computed for different midspan deflections, loads and friction coefficients. The longitudinal shear failure is the most common failure phenomenon among open rib steel deck profiles and thus multiple studies were performed. The observation of a constant Zu value at the shear span of the bending test was novel and indicated that the Eurocode 4 Partial Connection Method was not capable to describe the complex longitudinal shear strength behaviour observed from the simulations. The dissertation concludes with the introduction of a new characterization parameter tu,mechanical to assess the composite slab design efficiency. The parameter is defined as the longitudinal shear strength tu computed from the simulations for a null friction coefficient. The new parameter proved to accurately characterize the performance of the different composite slabs studied in this dissertation when compared with the maximum loads from the laboratory tests. The combiation of the novel modeling and simulation methodology with the tu,mechanical computation enabled a new design process for steel deck profiles. The process developed an iterative computer-focused approach with the goal to reduce the reliance in the costly and tedious laboratory tests.
Les lloses mixtes formades per acer i formigó presenten una caracterització estructural complexa degut al comportament diferent dels seus dos materials constituents. Aquests materials pateixen diferents nivells de deformacions, grans desplaçaments i distribucions d'esforços complexes, i avui en dia encara es desconeixen molts dels aspectes fonamentals de la seva micro-mecànica. En conseqüència, les normatives actuals requereixen la realització d'assajos de laboratori per a cada llosa mixta a través d'un procés costós i llarg. La utilització de les simulacions numèriques basades en elements finits per l'estudi de les lloses mixtes es va introduir fa més de 25 anys com a un mecanisme per validar nous processos de disseny i per reduir els exigents requeriments dels assajos normatius de laboratori. Malgrat això, històricament i fins a dia d'avui les simulacions numèriques han patit simplificacions importants, com la realització de models a escala reduïda o amb geometries simples. La recerca introdueix inicialment una nova metodologia de modelat i simulació en lloses mixtes que aporta noves dades en el comportament del perfil de xapa nervada i de la llosa de formigó. Es van desenvolupar diferents models d'elements finits per a quatre perfils de xapa comercials per replicar els assajos de laboratori de flexió. Inicialment, es va implementar un procés d'optimització sistemàtic en els models d'elements finits, ja que tant els costos computacionals com la mida de les simulacions eren elevats. Els models tridimensionals van incloure la profunditat i pendent de les emboticions, el gruix de la xapa d'acer i l'angle del nervi, entre molts altres paràmetres geomètrics. Es van millorar simplificacions i limitacions habituals observades en recerca publicada anteriorment sobre la interfície formigó-acer, el factor d'adhesió i els factors de cohesió. Es va implementar el mètode de simulació de Newton-Raphson, que va permetre la consideració de no-linealitats en geometries i materials. La metodologia proposada va ser validada comparant-la amb els resultats experimentals dels assajos de flexió. A partir de la solidesa observada en les simulacions de flexió, es van desenvolupar nous models d'elements finits de l'assaig de pull-out per realitzar un estudi paramètric i de condicions de contorn. A partir de les simulacions, es van analitzar multitud de fenòmens micro-mecànics que no s'havien pogut detectar directament en el laboratori. Primer, es van caracteritzar les representacions dels eixos neutres i la desconnexió vertical entre el formigó i l'acer, i posteriorment es va demostrar l'existència de connexió parcial entre ambdós materials. Segon, es va definir una nova tensió vertical normal σshear per descriure les tensions verticals observades entre la xapa d'acer i la llosa de formigó. Tercer, es va calcular l'esforç longitudinal a rasant tu per a tota la longitud del nervi i per a diferents càrregues. L'observació d'un segment amb valor constant va validar una de les hipòtesis del Mètode de la Connexió Parcial de l'Eurocodi 4. Així mateix, també va posar de manifest que el model mecànic d'aquest mètode no era capaç de capturar la complexitat observada en les simulacions per l'esforç "τu". La recerca conclou amb la introducció d'un nou paràmetre de caracterització de l'eficiència de la llosa mixta anomenat "τu,mechanical". Aquest paràmetre es defineix com l'esforç longitudinal a rasant tu obtingut de les simulacions amb fricció nul.la. El nou paràmetre va caracteritzar correctament els diferents perfils comercials modelats quan van ser comparats amb la seva resistència última obtinguda en els assajos de laboratori. La combinació de "τu,mechanical" i la nova metodologia de modelat i simulació genera un nou procés de disseny per lloses mixtes. A través d'un procés iteratiu centrat en simulacions que optimitzen "τu,mechanical", el procés genera una proposta de disseny final de la xapa d'acer, sense la necessitat de realitzar cap assaig al laboratori.

Abstract:
The behaviour of composite steel-concrete slabs under fire has attracted considerable attention over recent years and has led researchers to develop performance based models capturing the phenomena observed during fires. However, while the limit load proposed defined corresponds to fracture of the reinforcing mesh, the criterion employed is semi-empirical ignoring fundamental issues such as the bond slip characteristics. A recent model has addressed this issue for lightly reinforced beams, considering the bond slip response of the reinforcement along with other salient problem characteristics, however, it becomes complex for practical application when extended to slabs. In the current work, novel models are developed for the assessment of the failure load of lightly reinforced concrete slabs under fire conditions, considering simply supported rectangular slabs with and without planar edge restraints. In the limit, this load corresponds to the failure load of composite slabs under fire, since fire tests have demonstrated that the steel deck de-bonds leaving a lightly reinforced concrete slab. The developed models account for the temperature effect on the geometric and material properties, and they consider the tensile membrane action developed at large deflections. The deflected shape, used as the basis of model formulation, was observed experimentally to match the failure mode described by yield line theory, and in the developed models, it is assumed that cracks forming along the yield lines, penetrate through the slab depth. The strain concentration in the reinforcement along these cracks is established by considering the bond slip characteristics, and the failure load is determined as that corresponding to a specific rupture mechanical reinforcement strain. Comparisons against the non-linear finite element analysis program ADAPTIC and experimental results are presented along with case studies highlighting the influence of various parameters. Simplified versions of the proposed models are also presented for direct use by designers to assess the failure of composite slabs under elevated temperatures.

Abstract:
Innovative new flooring systems utilising lightweight fibre reinforced polymer composite materials may have the significant potential to offer both economic and performance benefits for infrastructure asset owners compared to conventional concrete and steel systems. Over recent years, a range of prototype floor systems using fibre reinforced polymer composites have been developed by researchers at the University of Southern Queensland. However before such structural systems can be widely adopted by industries, fundamental understanding of their behaviour must be improved. Such work will allow for the development of new design and analysis procedures which will enable engineers to efficiently and accurately design and analyse such structures. This dissertation presents an investigation into a new two-way fibre reinforced composite floor slab system. The proposed new two-way slab system is, in essence, a sandwich structure with an innovative hollow core made from a castable particulate filled resin system. The key focus of this dissertation is the development of a new analysis tool to analyse the two-way fibre reinforced composite slab and facilitate subsequent parametric studies into slab configurations for concept refinement. The detailed 3D finite element analyses and experimental investigations are performed to verify the new analysis tool, and provide more detailed insight into the structural behaviour of this new two-way fibre reinforced composite slab. Comparisons with detailed 3D FEA and experiments illustrate that the simplified analysis tool is capable of providing sufficient accuracy for the preliminary analysis of a slab structure. Moreover, the 3D finite element analyses agree well with the experiments, and it is concluded that the behavioural responses of the proposed new slab structure can be reliably predicted. The experimental results show that this new slab concept exhibits quite a robust static behaviour and is likely to have a robust fatigue performance.

Abstract:
The purpose of this research is to evaluate and compare the influence of four types of secondary reinforcement on various component strengths related to composite slabs. These components include the composite slab strength under uniform load, the strength of two types of shear connectors used with composite beams and joists, composite slab strength due to a concentrated load, and the flexural toughness and first-crack strength of fiber-reinforced concrete using ASTM C1018 (1998) standard test. The performance of the specimens reinforced with fibers are compared with that of the specimens reinforced with welded-wire fabric (WWF), with the purpose of determining if fiber-reinforced concrete can be used as an alternative to WWF.

Abstract:
As cold-formed steel decks are used in virtually every steel-framed structure for composite slab systems, efforts to develop more efficient composite floor systems continues. Efficient composite floor systems can be obtained by optimally utilizing the materials, which includes the possibility of developing long span composite slab systems. For this purpose, new deck profiles that can have a longer span and better interaction with the concrete slab are investigated. Two new mechanical based methods for predicting composite slab strength and behavior are introduced. They are referred to as the iterative and direct methods. These methods, which accurately account for the contribution of parameters affecting the composite action, are used to predict the strength and behavior of composite slabs. Application of the methods in the analytical and experimental study of strength and behavior of composite slabs in general reveals that more accurate predictions are obtained by these methods compared to those of a modified version of the Steel Deck Institute method (SDI-M). A nonlinear finite element model is also developed to provide additional reference. These methods, which are supported by elemental tests of shear bond and end anchorages, offer an alternative solution to performing a large number of full-scale tests as required for the traditional m-k method. Results from 27 composite slab tests are compared with the analytical methods. Four long span composite slab specimens of 20 ft span length, using two different types of deck profiles, were built and tested experimentally. Without significantly increasing the slab depth and weight compared to those of composite slabs with typical span, it was found that these long span slabs showed good performance under the load tests. Some problems with the vibration behavior were encountered, which are thought to be due to the relatively thin layer of concrete cover above the deck rib. Further study on the use of deeper concrete cover to improve the vibrational behavior is suggested. Finally, resistance factors based on the AISI-LRFD approach were established. The resistance factors for flexural design of composite slab systems were found to be f=0.90 for the SDI-M method and f=0.85 for the direct method.

Abstract:
The main aim of this thesis is to develop an insight into the behaviour of composite floors that utilise steel beams acting in combination with precast concrete hollow core floor slabs and to produce design recommendations for use by industry for this type of construction. Full scale bending tests of proprietary precast prestressed concrete hollow core unit floor slabs attached through 19mm diameter headed shear studs to steel Universal Beams (UB) have been carried out to determine the increased strength and stiffness when composite action is considered. The results show the bending strength of the composite beam to be twice that of the bare steel beam, and its flexural stiffness to be more than trebled. In addition to the beam tests, isolated push-off tests and horizontal eccentric compression tests were used to study the horizontal interface shear resistance of the headed studs and the strength of the slab, respectively. Maximum resistances were compared with the predictions of the Eurcode EC4, and a reduction formula for the precast effect derived. In addition to the experimental investigations, finite element (FE) studies were also conducted using the FE package ABAQUS to extend the scope of the experimental work. Results show a 2-dimensional plane stress analysis to be sufficiently accurate, providing the correct material input data obtained from isolated push-off and compression tests are used. The FE model for the composite beam was designed and validated using the full scale beam tests. A parametric study, involving 45 analyses, was carried out to cover the full range of UB sizes and floor depths used in practice. From the finite element work, design charts are formulated which may be used to simplify the design rules. Given the results of this work, a full interaction composite beam design may be carried out using the proposed design equations. The results show that precast slabs may be used compositely with steel UB's in order to increase both flexural strength and stiffness at virtually no extra cost, except for the headed shear studs. The failure mode is ductile, and may be controlled by the correct use of small quantities of transverse reinforcement and insitu infill concrete.

Abstract:
<p>Steel-concrete composite structures are widely used throughout the world for buildings and bridges. A distinguishing feature of this form of construction is the combination of concrete and steel components to achieve enhanced structural performance. <p>The time-dependent response of concrete and its infl uence on the service behaviour and design of composite structures are the main focus of this SED. For the fi rst time, a publication combines a state-of-the-art review of the research with the available design specifi cations of Europe, Australia and New Zealand, and USA. This publication intends to enhance the awareness of the service response of composite structures and of the latest research and standards’ developments. It is aimed at designers and researchers alike. <p>The review of research available in open literature is provided and arranged according to structural typologies, i. e. slabs, beams, and columns. It serves as background information for current service design rules and provides insight into the most recent research advancements. The review of available design guidelines presents the similarities and differences of the recommended service design procedures infl uenced by concrete time effects. Selected case studies of building and bridge projects show possible design approaches and the rationale required when dealing with the time-dependent response and design of composite structures. The authors of this publication are design engineers and academics involved in the service design and research on the time-dependent response of composite structures.

Abstract:
<p>This chapter presents a state-of-the-art review of work published to date on the time-dependent response of composite steel-concrete slabs. The key components of this form of construction are introduced in the first part of the chapter, followed by a review of the time-dependent behaviour of the concrete and how it affects the in-service response of composite slabs. Throughout the chapter, particular attention is given to recent experimental and modelling work related to concrete time effects, and how these affect the in-service response of composite slabs, including the development of non-uniform shrinkage gradients that have been recently shown to occur in composite floors due to the inability of the concrete to dry from its underside because of the presence of the profiled steel sheeting.</p>

Abstract:
<p>Increases in traffic loads led to extensive fatigue damages to existing orthotropic steel roadway slabs. Reinforced concrete slabs are less susceptible to fatigue but considerably heavier. With the so-called ortho-composite-slab a light and robust construction is developed as an alternative to ex- isting construction methods for bridge decks. The experimental test program planned within the framework of the AiF-FOSTA research project P 1265 [1] is used to determine the load-bearing and fatigue behavior of ortho-composite-slabs with composite dowel strips. The following article pre- sents the construction and the experimental test program.</p>

Abstract:
This paper presents an experimental study on demountable shear connectors in profiled composite slabs. Overall, three groups of push-off tests were conducted to assess the shear capacity, stiffness and ductility of the shear connectors. In all the specimens, a pair of shear studs were used per trough and were bolted to each side of the flange of a loading beam. Different concrete strength, embedment height of the shear studs and reinforcement cage were considered. Particularly, a joint was made between the pair studs in two groups of specimens when casting and formed two completely separate slabs per half specimen, to evaluate the load transfer between the pair studs. The experimental results showed that the shear capacity and behavior of the demountable connectors in separate slabs and continuous slab were both similar to the welded connectors and could fulfill the 6mm minimum ductility requirement stated in Eurocode 4 if proper embedment height of connector was used. The shear capacities of the tested specimens were compared against the calculated results obtained from the equations used for welded shear connectors in Eurocode 4 and bolted connections in Eurocode 3. Generally, the Eurocodes prediction underestimated the shear capacities of the push-off specimens.

Abstract:
The threat of terrorist attack against civil infrastructure in the US and other countries has led to the need to better understand the response of structures and structural components to an impulsive air blast overpressure. One scenario that is present in many cities is delivery trucks entering basement or street level loading/unloading areas. A bomb present in one of these delivery trucks could cause considerable damage to the floor slab (and consequently the building) above the blast by causing a vertical uplift, a condition that the slab was not designed to resist. Traditional methods to retrofit floor slabs to resist an upwards blast pressure require that additional tension sustaining reinforcing bars (rebars) be placed near the slab upper surface. This reinforcing method is costly, difficult to produce, and adds additional weight to the overall structure in building retrofit situations. Another approach to reinforcing the slab is to bond light-weight, high strength fiber composite material to the slab upper surface as a means of resisting the tensile forces from the slab upward motion. This paper presents results from an effort to simulate the response of a reinforced concrete floor slab with a fiber composite retrofit subjected to a blast overpressure. The simulations were performed using the Weidlinger Associates’ FLEX [1] finite element code for structural response calculations. The MAZ [2] computational fluid dynamics code was used to generate blast pressure. This paper will discuss the modeling effort used to predict the response of fiber composite retrofitted slabs and compare the computational analysis to test results1.

Abstract:
Earthquake disasters in the United States account for $6.1 billion of economic losses each year, much of which is directly linked to infrastructure damage. These natural disasters are unpredictable and represent one of the most difficult design problems in regard to constructing resilient infrastructure. Structural floor and roof diaphragms act as the horizontal portion of the lateral force resisting system (LFRS), distributing the seismically derived inertial loads out from the heavy concrete slabs to the vertical LFRS. Composite concrete-filled steel deck floor and roof diaphragms are ubiquitously used in commercial construction worldwide due to the ease of construction and cost-effective use of structural material. This report presents a series of composite steel deck diaphragm Push-out tests at full scale that explore the effect that cyclic loading has on the strength of steel headed stud anchors. The effect that cyclic loading has on structural performance is explored across the variation of material and geometric parameters in the Push-out specimens, such as concrete density, steel headed stud anchor placement and grouping, steel deck orientation, and edge conditions. As compared to prior tests in the literature, the push-out tests conducted in this work have an extended specimen length that includes four rows of studs along the length rather than the typical two rows of studs, and an ability to impose cyclic loading. This provides novel insight into force flows in the specimens, failure mechanisms, and load distribution between studs and stud groups.

Abstract:
A patented active porcelain enamel coating improves both the bond between the concrete and steel reinforcement as well as its corrosion resistance. A Small Business Innovation Research (SBIR) program to develop a commercial method for production of porcelain-coated fibers was developed in 2015. Market potential of this technology with its steel/concrete bond improvements and corrosion protection suggests that it can compete with other fiber reinforcing systems, with improvements in performance, durability, and cost, especially as compared to smooth fibers incorporated into concrete slabs and beams. Preliminary testing in a Phase 1 SBIR investigation indicated that active ceramic coatings on small diameter wire significantly improved the bond between the wires and the concrete to the point that the wires achieved yield before pullout without affecting the strength of the wire. As part of an SBIR Phase 2 effort, the University of Louisville under contract for Ceramics, Composites and Coatings Inc., proposed an investigation to evaluate active enamel-coated steel fibers in typical concrete applications and in masonry grouts in both tension and compression. Evaluation of the effect of the incorporation of coated fibers into Ultra-High Performance Concrete (UHPC) was examined using flexural and compressive strength testing as well as through nanoindentation.

APA, Harvard, Vancouver, ISO, and other styles
Abstract:
This research project aims to examine the structural behaviour of stud shear connections with both solid concrete slabs and composite slabs under standard and modified push-out tests. A total of 27 push-out tests were carried out to provide test data of typical stud shear connections. It should be noted that the modified push-out tests were proposed in which the stud shear connections were subjected to combined shear and pull-out forces. Advanced finite element models using ABAQUS have also been established and calibrated carefully against the test data. Systematic numerical investigations are conducted to provide new understandings on load transfer mechanisms of these stud shear connections. Moreover, a comprehensive parametric study is carried out using various material properties of the concrete and various geometry of the profiled steel decking. A configuration parameter ηd and a reduction factor ηt are proposed for use in conjunction with the reduction factor kd given in EN 1994-1- 1 to incorporate the effects of installation positions of headed shear stud, trough widths of profiled decks, and presence of significant pull-out forces.

Abstract:
Shear connectors are devices that provide shear connection at the interface of steel girders and reinforced concrete slabs in composite structures to accomplish composite action in a flexure. The seismic response of composite structures can be controlled using properly designed shear connectors. This state-of-the-art review article presents considerable information about the distinct types of shear connectors employed in composite structures. Various types of shear connectors, their uniqueness and characteristics, testing methods and findings obtained during the last decade are reviewed. The literature, efficacy, and applicability of the different categories of shear connectors, for example, headed studs, perfobond ribs, fibre reinforced polymer perfobonds, channels, pipes, Hilti X-HVB, composite dowels, demountable bolted shear connectors, and shear connectors in composite column are thoroughly studied. The conclusions made provide a response to the flow of the use of shear connectors for their behaviours, strength, and stiffness to achieve composite action.

NUMERICAL ANALYSIS AND EVALUATION OF EFFECTIVE SLAB WIDTH OF COMPOSITE CONTINUOUS BEAMS WITH SEMI-RIGID JOINT. The Hong Kong Institute of Steel Construction, December 2021. http://dx.doi.org/10.18057/ijasc.2021.17.4.1.

Abstract:
The characterization of the structural behavior of composite beams is directly affected by the determination of the effective slab width. Various codes propose their own definitions of the effective width based on the beam span and the slab width parameters. However, the evaluation of the effective width may be influenced by other parameters. The aim of this work is to determine the most important factors affecting effective width for continuous composite beams with semi-rigid joints using numerical simulations. A three-dimensional finite element model of a composite continuous beam using explicit-solver available in ABAQUS is developed. The proposed model is validated through comparisons to available experimental results. A modified model is proposed based on the so-validated model to study the influence of the composite beam-column joint stiffness on the effective width. Then, both numerical models are used to perform an extensive parametric study to investigate the influence of various parameters on the estimation of the effective slab width. The influence of slab width, the shear connection degree, and composite joint stiffness are particularly analyzed to find out the most important parameters influencing the effective width so that simplified equations for the calculation of the effective slab width are proposed.
