Analytical Study on Bond Slip Behaviour of CSRC Slabs
A composite slab with profiled steel deck and concrete are mainly used in steel framed building systems. The two major functions of profiled steel deck are it serves as a permanent formwork during the casting of concrete and after the concrete has dried and hardened, serve as a tensile reinforcement. The horizontal slippage is because of to the longitudinal shear stress developed when ultimate shear force is reached. In order to reduce the slippage, the steel deck should be properly connected to concrete and also to each other by mechanical shear connectors like stud shear connector, perfobond ribs and their combinations. Here a parametric study on different shear connector configurations including bolts and perfobond shear connector are done. The composite slab is modelled and analysed under push test in ANSYS to find out the effective shear connector configuration and also to find the effectiveness of shear connectors.
