Abstract:In the present paper the results of a three-dimensional finite element analysis of punching failure in reinforced concrete slabs are presented and discussed. The analysis is carried out using the three-dimensional special purpose finite-element code MASA. To demonstrate that the finite element code is able to realistically predict the punching failure, a punching test on an interior slab-column connection is analyzed. The results of the analysis are compared with the test results. Subsequently, a parametric study is performed where the concrete properties and the reinforcement ratio are varied. To investigate the size effect, for a fixed set of material parameters the slab geometry is scaled in a size range of practical interest.
