Abstract

The simulation of reinforced concrete columns using the finite element method is examined in this study. Different assumptions for the bond between the steel and the concrete are investigated and results are compared with available experimental data. The effect of concrete shrinkage is also considered. According to these results, the different assumptions are validated and appropriate recommendations are proposed for the accurate simulation of reinforced concrete columns. The modeling of the bond between the steel and the concrete is found to be essential as it induces an additional deflection in the response of the columns that can be significant. The concrete shrinkage effect is found to be of major importance for the accurate prediction of the behavior of the reinforced concrete columns. The simulation of concrete shrinkage results in a significant reduction of the stiffness of the columns due to biaxial stress state conditions.
