Calculating the load-deflection behaviour of simply-supported composite slabs with interface slip
Abstract Interface slip between the concrete and the profiled steel sheet in a composite slab may lead to a significant drop in the stiffness and the strength of the slab. This paper presents a numerical procedure which can be used to calculate the behaviour of the slab, including the interface slip, the deflection and the strength of the slab. Nonlinear material properties are assumed and the interface slip is considered to be resisted by the combined resistance of mechanical interlock and friction between the concrete and the profiled steel sheet. The deflection and the interface slip of the slab are calculated from integration of the cross-section curvatures and the slip strains which are determined from analyses of the composite cross-sections along the slab. By repeating the deflection calculation for each increment of load, the load - deflection behaviour of the slab is obtained. The slab is considered to fail when any cross-section along its length reaches its peak moment.
