Dissertation note: Thesis (M.Sc.) - Cairo University - Faculty of Engineering - Department of Civil Engineering Summary: Punching shear is one of the critical concerns in design of flat slab systems. The new Egyptian code ECP203-2018 allowed the use of shear reinforcement in resisting punching shear.This research is conducted to investigate the effect of different parameters regarding shear reinforcement on the punching capacity of flat slabs. These parameters include yield stress of stirrup, extension of stirrups from column face along slab span, slab thickness and the use of multiple leg stirrups against closed stirrups.The experimental program in this research includes testing 8 slab specimens with dimensions of (1200x1200) mm with thickness of 160mm and 200mm. The results of the experimental work were compared to provisions of ECP203-2018, ACI318-19, and EC2 codes.The results showed that increasing slab thickness from 160mm to 200mm increased the punching capacity by 20% for slabs without stirrups and 50 % for slabs with stirrups. Using closed stirrups increases punching shear strength of flat slabs as compared to multiple-leg stirrups
