Composite deck slab floors with profiled steel decking are becoming common place in many nations due to their ability to facilitate quicker, lighter, and more affordable construction. In order to enhance its shear-bond properties, rolled embossments are incorporated into the concrete as well as steel deck to form the composite interaction that creates the slab. The strength of the contact between the concrete layer and profiled steel sheeting determines the composite deck slabs’ strength. A composite deck slab with a profiled steel sheet is made by pouring concrete over the steel sheet. Two primary purposes of a profiled steel sheet are that it serves as formwork during the concrete-setting process and as tension reinforcement once the concrete has solidified. Before moving further with the design of the entire composite slab, it is imperative to verify the sheet's suitability for use during the building phase. This study is focused on examining the effects of various parameters on the behavior of composite slabs. ANSYS software has been used to create 3-D Finite Element Models of Conventional Slab and Composite slabs. ANSYS was used to analyze these models in order to examine their structural behavior and functionality and it demonstrates their ability as sustainable alternatives to the standard slab. The use of Profile steel sheet resulted in a decrease of Volume by about 29% when compared to Conventional slab which further resulted in 3% lesser Deformation. Moreover, the stress experienced by the Composite slab decreased by about 32%. These results demonstrate the structural and financial advantages of using these cutting-edge, environmentally friendly building techniques.
