Creep and Shrinkage Effects on Steel-Concrete Composite Beams
Predicting the long-term behavior of steel-concrete composite structures is a very complex systems problem, both because obtaining reliable information on material properties related to creep and shrinkage is not straightforward and because it is not easy to clearly determine the correlation …

Finite element modelling of shear connection for steel-concrete composite girders
… the behaviour of headed stud shear connectors in composite girders with solid slabs and precast hollow core slabs. The finite element package ABAQUS was used to conduct the analysis. Push-off tests with both types of slabs were simulated taking into consideration all material nonlinearities of the …

Fatigue and static behaviour of post-tensioned steel-concrete composite beams
Strengthening steel and concrete composite (SCC) bridge superstructures using post-tensioned steel tendons offers many advantages. Since bridge structures are usually exposed to fatigue cycles, understanding the fatigue behavior of strengthened composite beams is vital. Also, bridges in practice …

Steel, steel/concrete composite and reinforced concrete beams and columns exposed to fire
… results with a number of experimental results on steel, concrete and composite beams and columns from literature and with the experiments carried out under this research programme. Experiments were carried out on seven columns with non-uniform temperature distribution along the length and across …

On the Fatigue of Headed Shear Studs in Steel-Concrete Composite Bridge Girders
<p>Shear connectors are commonly used in steel bridges to join the concrete deck and steel superstructure, providing a mechanism for shear transfer across the steel-concrete interface. The most common shear connector is the headed shear stud. In the current AASHTO LRFD Bridge Specifications on …

The Viability of Steel-Concrete Composite Girder Bridges with Continuous Profiled Steel Deck
… of constructing short-span, simply supported composite steel girder bridges. However, because shear studs can only be welded to the girder through the steel deck at rib locations, the number of shear stud locations is limited to the number of ribs in the shear span while the spacing of the …

Large-scale testing of a steel-concrete composite floor system under column loss scenarios
… project that studied the structural integrity of steel gravity framing systems composed of steel beams and girders with composite concrete slab on steel deck. Steel simple beam-column connection tests were conducted at the University of Washington, steel-concrete composite slab tests were …

Characterization of behavior of steel-concrete composite members and frames with applications for design
Steel-concrete composite frames are seeing increased use in practice. Their excellent structural characteristics, including high strength, stiffness, and ductility, make them an appealing option for many building configurations. However, there exist gaps in the knowledge of behavior and the design …

Feasibility of fiber reinforced composite materials used in highway bridge superstructures
Composite materials are considered here as structural materials of highway bridge superstructures. Bridge deck designs can be done according to <i>AASHTO</i>¹ specification and elastic design concepts. In order to evaluate the feasibility of composites as structural materials of highway bridge …

Assessment of beam-to-column joint behaviour in steel-timber composite systems
Reinforced concrete slabs are among the structural components with the highest levels of embodied energy and carbon. Accordingly, replacing conventional reinforced concrete slabs with timber slab can potentially reduce the embodied energy and carbon footprint and provide opportunities for effective …

Web crippling of hot-rolled beams at stiffened-seat connections
… three full-scale tests were conducted on steel-concrete composite beams to verify the accuracy of the proposed equation. Finally, the current web crippling equations and the proposed equation are compared for all available end web crippling data, and conclusions and recommendations are …

Numerical Modeling of Composite Systems: Composite CFT Connections and Composite Beams
The use of concrete-filled tubular composite members and composite beams has been implemented in many structural systems due to their robust structural performance, constructability, and inherent synergy when the steel and concrete components are properly designed and detailed together. While …

The numerical modelling of composite floors exposed to fire
… with the influence of fire on the behaviour of steel concrete composite floors. A theory has been developed to calculate deflections during the fire and the ultimate strength ofthe composite floor under such conditions. The solution is based on the finite difference method. It takes …

Progressive Collapse Assessment of Steel and Concrete Composite Structures Subjected to Extreme Loading Conditions
… work focuses on the study of the behaviour of steel-concrete composite structures subjected to a column loss, and proposes a global overview to quantify the robustness of such systems subjected to this hazard scenario. The description of validated finite element models and of a new analytical …

Numerical and experimental methods for seismic risk assessment of civil and industrial structures
… throughout hybrid simulations where the steel storage tank is numerically modelled while, conversely, the physical substructure encompasses the coupled piping network. Besides, ground motions for dynamic tests are synthetized based on a stochastic ground motion model whose input …

Experimental Evaluation and Analytical Modeling of Shear Bond in Composite Slabs
The strength and behavior of composite slabs are governed by the shear interaction between the concrete and the steel deck. The interaction property depends on several factors and it is not possible to express the relationship from a purely analytical basis. As such, analysis and design methods …
