The profiled decking sheet must provide the resistance to vertical separation and horizontal slippage between the contact surface of the concrete and the decking. It also permits transfer of shear stresses from the concrete slab to the steel deck. The horizontal slippage between the concrete and the steel deck will exist due to the longitudinal shear stress when the sheer force of the shear connectors reaches its ultimate strength. Thin-walled cold-formed profiled steel decks used to build the slab specimens are made of structural quality steel sheets conforming to ASTM and IS 1079. A galvanized surface coating with an average thickness of 60 gsm is coated on each face of the steel deck. The thickness of the Steel sheet ranging from 0.80 mm to 2.00 mm, depending on load parameters of the building. Composite slab reinforced with profiled steel decking sheet means there is a provision in the system for positive mechanical interlock between the interface of the concrete and the steel deck by means of embossments.
