Abstract

Introducing the behavior of reinforced concrete materials is generally considered as one of the complex parts of modeling in finite element software. Thus, entering accurate material information has an effective role in software output results. There are several methods in ABAQUS software for nonlinear analysis of reinforced concrete, one of which is the use of a Concrete Damage Plasticity (CDP) model. In this method, entering the mechanical properties of concrete is of special importance, so that in case of insufficient data entry, many errors are created in the results and sometimes cause no convergence despite spending a lot of time analyzing in the software. In numerical modeling in ABAQUS using the CDP method, two conditions must be observed. Firstly, the sing of the plastic strains of the concrete are positive and secondly, with increasing the concrete strain, the plastic strains of concrete are also upward. These conditions cause the elimination and reduction of some points in the input information of concrete materials in the CDP method. In this study, the analysis procedure is performed by varying the number of stress points and tensile strain and tensile damage parameter (dt), this analysis is repeated. The results obtained by nonlinear analysis of reinforced concrete structure due to the reduction of the number of points of the mentioned parameters are specified as force-displacement curves and the results show that by reducing the number of these points, with a minor error, the time of structural analysis is significantly reduced.
