Experimental Investigation and Comparison of Composite Slab with Perpendicular and Skew Type Steel Decking

Abstract

Composite floor is widely used in the building industry in the last decades. The casting of concrete is carried out on corrugated steel plate which is supported by beams. The efficiency of composite slabs depends on composite action between the steel and concrete structural members. Composite slab with profiled steel decking has proved over the years to be one of the simpler, faster, lighter and economical constructions in steel-framed building systems. This system is well accepted by the construction industry due to the many advantages over other types of floor systems.
Composite slab reinforced with profiled steel decking sheet means there is a provision in the system for positive mechanical interlock between the interface of concrete and the steel deck by means of embossments. The profiled decking sheet must provide resistance to vertical separation and horizontal slippage between the contact surface of the concrete and the decking sheet. It also permits the transfer of shear stresses from the concrete slab to the steel deck. The main objective of this project is to investigate and compare the composite slab with perpendicular and skew type steel decking.
