Currently, RC flat slabs are being used commonly because of their advantages. Punching shear failure is oneof the governing failure modes of RC flat slabs without column capital and drop panels. In this paper, theprovisions for predicting the punching shear capacity of two-way reinforced concrete (RC) flat slabs withoutshear reinforcement including ACI 318-19, Eurocode 2 and TCVN 5574:2018 provisions are reviewed by meanof considering the influences of the main parameters (effective depth, compressive strength of concrete, loadedarea, reinforcement ratio). A total of 169 test results collected from the literature were used to compare withthe provisions. The aim of this study was to evaluate the level of applicability of predicting the punching shearcapacity of two-way RC flat slabs according to these provisions. The comparison results indicated that theEurocode 2 provision provides the most accurate prediction of punching shear capacity of two-way RC flatslabs.
