Nonlinear finite element model calibration of a reinforced concrete column with distributed plasticity

Abstract

Nonlinear finite element models, whenever is possible, shall be validated using experimental data. The efficiency of the nonlinear analysis depends on the choice of finite element models parameters. In the present work the calibration is conducted with the goal of observe and minimize the difference between the experimental data and the nonlinear finite element models, using two distributed plasticity modelling approaches. Several models with different parameters of distributed plasticity are used herein and compared against experimental data. The results show that the nonlinear analysis, when associated to a proper modeling strategy, is capable to successfully simulate experimental data.
