A Review on Performance Analysis of Steel Concrete Composite Section

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. Double steel-concrete composite continuous beam is a new structural system developed on the basis of single steel concrete one, in which there is also a bottom reinforced concrete slab connected to a steel profile in the negative moment regions through the head studs, therefore with two interfaces. Ansys 19.2 computer program has been used to develop a three-dimensional nonlinear finite element model in order to investigate the fracture behaviours of continuous double steel-concrete composite beams, with emphasis on the beam slab interface. Three beam models with varying number of the steel sheets in concrete beam have been addressed. The associated constitutive results such as the ultimate loads, the maximum deflections, the interface slip and slip strain values are presented.
