الملخص

The aims of this study is to present a new simple accurate equation to determine the punching shear strength of normal and high strength reinforced concrete flat slabs. The punching shear strength prediction of the proposed equation is compared with the experimental data collected from 58 experimental cases. The proposed equation takes into account some effects such as concrete compressive strength, slab depth, slab tension reinforcement ratio at the critical section, shape and dimension of column, and the position of critical section. The proposed equation gives a better agreement with experimental data than AS3600, CEB-FIP MC-90, ECP, ACI-318, and BS-8110. It is noticed that the tension reinforcement ratio has an effect on the punching shear strength where increasing the tension reinforcement ratio from (0.6%) to (2.2%) increase the strength of punching shear strength by (17%).
