Punching shear failure of flat concrete slabs is a complex phenomenon with\nbrittle failure mode, meaning sudden structural failure and rapid decrease of\nload carrying capacity. Due to these reasons, the application of appropriate\npunching shear reinforcement in the slabs could be essential. To obtain the\nrequired structural strength and performance in slab-column junctions, the\neffect of the shear reinforcement type on the punching resistance must be\nknown. For this purpose, numerous nonlinear finite element simulations were\ncarried out to determine the behavior and punching shear strength of flat\nconcrete slabs with different punching shear reinforcement types. The efficiency\nof different reinforcement types was also determined and compared.\nAccuracy of the numerical simulations was verified by experimental results.\nBased on the comparison of numerical results, the partial factor for the design\nformula used in Eurocode 2 was calculated and was found to be higher than\nthe actual one.
