The structural performance was Accepted 5 November 2018 investigated in terms of punching shear capacity of the reinforced concrete flat slab. The study Available online consisted of a laboratory punching shear test on the contra-flexure bound slab of dimension 5 November 2018 Keywords 1060mm 1250mm by 130mm thick in a reactant test frame using a 500kN load cell. Results of Reinforced the experimental study was validated using finite element based numerical method. Both Concrete experimental and numerical results show that increase in tensile strength of concrete increases Slab punching shear capacity of the connection. It was also observed that punching shear failure of the Punching connection depended largely on concrete shear strength. This study has also revealed that punching Shear-head shear occurs when concrete shear strength is reached irrespective of the robustness of the shear- Numerical head connection. 2019 Growing Science Ltd.
