Approaches for suitable modelling and strength prediction of reinforced concrete slabs

Despite the advances on the understanding and modelling of shear and punching shear failures, the application of actual design models to some stations remains still complex. In addition, other significant phenomena such as compressive membrane action and moment redistribution may also develop influencing the shear/punching strength. The procedure is based on nonlinear finite element analysis of RC slabs modelled using mult-layered shell elements. Nonlinear finite element analyses (NLFEA) results obtained using PARC-CL crack model, implemented at the University of Parma in Abaqus Code, are post-processed according to the failure criterion of the Critical Shear Crack Theory (CSCT) to predict the punching shear strength of continuous slabs.
