Finite Element Analysis of Composite Slab With Intermediate Stiffeners

The use of steel deck in combination with concrete results in an optimum solution bringing with it great advantages such as no form work, quick installation, and reduced dimensions and weight to construction of building floors. Essentially behaviour of composite slabs is governed by the horizontal shear bond at the interface of the steel deck and the concrete. The profile steel deck serves as tension reinforcement.The composite flooring system essentially consists of one-way spanning structural components. The slab spans between the secondary floor beams, whereas these secondary beams span transversely between the primary beams. In this paper, FE modelling of composite slab with considering different parameters like thickness of profiled steel sheet and number of intermediate stiffeners has been carried out by using ANSYS Workbench-14 software. Analysis was carried out to know the overall and load-deflection behaviour of the composite slab. It has been observed that as the thickness of sheet increases, deflection decreases for the constant load. Furthermore, the analysis shows that the intermediate stiffeners play major role to reduce the deflection.
