Abstract: Sandwich components are multilayered materials made up of bond between high strength skins facing low density material. The primary target of this investigation was to discover flexural conduct of reinforced solid sandwich slab under punching shear. The experimental and numerical investigation is done on reinforced concrete sandwich slabs of dimensions 1000 mm x 1000 mm x 150 mm. The experimental programs were performed to assess the influence of same loading and support conditions. The sandwich slabs is provided with mesh reinforcement, extra reinforcement as spacing with variations of percentage of tension reinforcement (0.49%, 0.44%, 0.39% and 0.34%) and shear connectors has analyzed. The result shows 0.49% reinforcement gives better result when compared to other slabs.
