Abstract: This paper presents a study on the structural performance of a modified shear-head assembly for edge steel column embedded in reinforced concrete slab. The structural performance was investigated in terms of punching shear capacity of the reinforced concrete flat slab. The study consisted of a laboratory punching shear test on the contra-flexure bound slab of dimension 1060mm × 1250mm by 130mm thick in a reactant test frame using a 500kN load cell. Results of the experimental study was validated using finite element based numerical method. Both experimental and numerical results show that increase in tensile strength of concrete, increases punching shear capacity of the connection. It was also observed that punching shear failure of the connection depended largely on concrete shear strength. This study has also revealed that punching shear occurs when concrete shear strength is reached, irrespective of the robustness of the shear-head connection.
