DEVELOPING CONCRETE DAMAGE PLASTICITY MODELBY MAZARS DAMAGE

The concrete damage plasticity model, which is widely used in the analysis of concrete structuresand also in ABAQUS software, is specifically composed of two parts: damage mechanics andplasticity. Based on this, the performance of this model has been studied by numerous researchers andeach of them has improved this model by applying some modifications. One of the reliable models inthis field is the model presented by Koh et al., in where it is necessary to enter the arbitrary tensile andcompressive curves of the studied concrete. In this study, for the input curves, simplified uniaxialstress–strain curves of concrete are added to the model, and also the original damage model is replacedby Mazars concrete damage model and its performance under monotonic loading is discussed
