Summary:In this study, anon-linear 3D numerical analysis using ANSYS was performed to investigate the influence of slab and column dimension on the punching shear capacity of the corner slab-column connection. Most research studied the punching shear stress, but none of them studied the distribution of punching shear stress, which was assumed to be linear in different codes. Verification models have been used to simulate existing experimental data. Two factors were taken into consideration for their influence on the punching shear strength of the concrete: the slab aspect ratio, column aspect ratio, and other factors are constant. Therefore, twenty-one models of different slab and column dimensions were investigated, and a comparison between the results obtained by the finite element analysis and the numerical results was made. Also, a comparison between shear stresses computed using two different methods in the Egyptian code, the simplified method, and the detailed method, and compare them with the Ansys models.
