The use of composite structures is increasingly present in civil construction works. Steel-concrete composite beams, particularly, are structures consisting of two materials, a steel section located mainly in the tension region and a concrete section, located in the compression cross sectional area , both connected by metal devices known as shear connectors. The main functions of these connecto...

Abstract The widely used steel-concrete composite structures can fully utilize the high strength of steel and relatively compressive concrete. In service stage structures, shear connectors not only subjected to forces, but also pull-out loading. process is accompanied by crack initiation propagation order accurately analyze discontinuous capacities connectors, a zero-thickness cohesive zone ele...

Typical insulated precast concrete sandwich panel (PCSP) systems are composed of two wythes separated by a layer insulation. The structural behavior PCSP heavily depends on elements between known as connectors, which ensure they work whole. Double shear tests were carried out 58 specimens reinforced with basalt fiber-reinforced polymer (BFRP) connectors; failure modes, load displacement curves ...

In this paper, a new roofing system is introduced, which is constructued using the precast composite sandwich panels. This roofing sandwich panels system consists of three kinds of precast concrete sandwich panels including capital panels, beam or between columns panels, and slab or middle panels. The panels are composed of three layers; A high strength reinforced concrete top layer. A thick la...
