Abstract

This paper attempts to emphasize the experimental study on feasibility of Triangular perfobond rib shear connector in composite slab with cold formed steel beam. This rib shear connector is a feasible alternate to the existing type of connectors like shear studs etc., this perfoplate has triangular hole of size (30 × 50 mm) in the CFS plate of (500 × 40 mm) with two different positioning of triangular hole, one facing the flange (TR1) and the other facing opposite to flange (TR2). Vertical compressive force applied in Universal Testing Machine to find the shear capacity of the new connector in a composite slab. There is an increase in composite interaction which results in both the triangular perfobond have approximately equal load carrying capacity, but the slip behaviour is comparatively higher in the triangle head facing opposite to the flange (TR2). According to the failure phenomenon in ultimate loading state, the failure mechanism of perfobond rib shear connectors was analysed and the results indicates that brittle failure always occurs in perfobond rib connectors. The influence of the perfoplate connector configuration on the load bearing capacity and structural improvement was discussed.
