In the several codes and standard equations for the punching shear strength of reinforced concrete slabs, the cover thickness is not an influencing factor of the punching shear strength. 16 specimens of reinforced concrete slabs with various cover thicknesses are selected in the tests. The punching shear strength is found to increase with the increase of the cover thickness, in a nolinear way. The mechanism of the impact of the cover thickness on the concrete slab strength is analyzed based on a comparison between the calculation results and the test results, and finally, a new calculation method is proposed through the evaluation of the incipient theoretical equation. Test data are compared with the provisions of CCES, and with the proposed equation of Matsui, a simplified equation is proposed, which enjoys a better accuracy.
