Nonlinear Analysis of Two Shear Walls Using Elastic Plastic Damage Model

摘要

In this paper, the elastic plastic damage model for concrete under static loading previously proposed by Hu Qi et al. is developed in ABAQUS via UMAT, and it is verified by the simulation of two shear wall members under horizontal loading. The simulation results indicate that this constitutive model can accurately predict typical nonlinear performances of reinforcement concrete shear walls. Using the proposed model one can get the damage distribution of reinforced concrete members which is helpful for researchers to get the failure pattern of structures.
