Shear bond characteristics of steel concrete composite deck slab

Steel-concrete composite slabs with cold-formed, profiled steel deck sheets are popularly used in steel-framed buildings. In these slabs, the platform acts as a working during construction and also tensile reinforcement under in-service load conditions. The shear bond capacity of slab is evaluated this study for two different profile sheets. Specifically, their behaviour investigated by casting testing twelve full-scale specimens using two-point loading system. addition, based on span length height, structural performance analysed terms load-displacement response, capacity, ductility index, load-slip behaviour. results show that most common failure all tested occurs due to longitudinal between concrete As complex phenomenon, empirical approaches evaluate mechanism deck. verification comparison experimental test performed conventional simplified m-k models depth. validated reveal an acceptable level reliability prediction each height m k interaction values.
