Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Civil Engineering Summary: This thesis has two objectives: The first objective is a pioneering step to furnish the theoretical basis behind the ACI 318 semi-empirical punching formula. Principles of the boundary element method (BEM) and the theory of elasticity are adopted to establish the rationale behind the punching shear stress equation proposed in ACI 318. The present research further substantiates this effort through developing a BEM - based software for checking punching limit state for columns of any irregular cross section shape a task that ACI equation falls short of satisfying. The second objective is proposed to the ACI equation for checking punching a new term in order to include the effects of warping. A novel method for estimating the effects of warping of slab internal columns on punching stresses is introduced. In doing so, new punching parameters and are presented and evaluated/calibrated to include the effects of warping on punching and moment transfer analysis
