Shear force distribution in rc slabs subjected to punching: Solid nonlinear fe anlayses
Paper in proceeding, 2016

Reinforced concrete two-way slabs without shear reinforcement are commonly used in many structural systems. The paper investigated the structural behavior of RC slabs subjected to punching failure using solid nonlinear FE analysis. The appropriate approach to model the support was investigated and the nontension spring was selected in the FE analysis. Nominal shear force distribution was studied for four type of slabs with different geometry of support, geometry of slab and layout of reinforcement. All the factors has been proved to influence the shear force distribution along control perimeter around the support. A new method based on shear field theory to calculate the effective control perimeter was validated in the study.
