This study presents an experimental investigation on the influence of embedded shearhead reinforcement (steel plate) on the punching shear strength of reinforced concrete slabs. This work includes the investigation and testing of one control slab and five scale models of slab-column connection simply supported along the four edges. A shearhead was made by using a steel plate with T-section stiffeners, the stiffeners were fabricated to be with two lines welded on the tension face of the plates. The main variables studied were the dimensions and thickness of the steel plate (used as punching resistance) .The results show that ultimate load capacity at failure increases by (16.48%) over the reference slab. Also, punching shear stress decreases about (29.24%) below the reference slab.
