Sandwich panel are being extensively and increasingly used in building construction because of their reduced dead weight, energy efficiency and aesthetic appearance. These slabs can be easily handled and erected. This work presents the experimental results of effect of shear connectors on flexural behaviour of sandwich slab panels. Truss shaped and trapezoidal shaped shear connectors have been used to study the shear interaction between the top and bottom layer of concrete. Self-Compacting concrete forms the top and bottom layer of concrete with Expanded poly Styrene as the middle layer. Few recommendations on the suitability of shear connectors have been proposed. The performance of trapezoidal shear connectors is superior than the truss shaped shear connectors. The longitudinal shear transfer between top and bottom layers of concrete and middle layer of expanded poly Styrene is better in trapezoidal shear connectors. The performance was analytically studied using Ansys software which verifies the experimental results.
