3D non-linear finite element analyses are conducted to assess the overall punching shear behaviour of post-tensioned flat plates using ANSYS. A parametric study was conducted aiming to investigate the effect of several factors on punching shear. Group (B) of 15 models was conducted to study the effect of moment transfer through the slab-column connection and tendon layouts in plan on punching. Group (C) of 6 models was conducted to study the effect of column size and column rectangularity on punching. Group (D) of 3 models was conducted to study the effect of presstressing reinforcement ratio on punching. Group (E) of 5 models was conducted to study the effect of tendon eccentricity, the vertical distance from slab center to tendons' CG(s) over column, on punching. Then, analysis results were compared to the predictions of the following codes; the American code, the Egyptian code, the Canadian code, the European code, and the British code
