Prediction of punching behaviour of RC slabs using continuum nonlinear FE analysis

Paper in proceeding, 2016

Failure of reinforced concrete (RC) slabs in punching has been a challenging problem for nonlinear finite element (FE) analysis. To improve the analysis approach, this study was conducted by developing a nonlinear FE analysis method for slabs subjected to punching failure, using three-dimensional continuum elements. The influence of several modelling choices were investigated by comparing such results as load carrying capacity, load-deflection response and crack pattern from the FE analyses with available experimental data. The proposed method show the possibility of accurately predicting the load-carrying capacity and realistically describing the behaviour of slabs.
