Numerical Simulation Of Reinforced Concrete Frame With Open-Infilled Brick Wall

In this paper, a 3D numerical model is developed to simulate the behavior of a Reinforced Concrete (RC) frame infilled with open walls. The numerical model is developed based on ABAQUS software, which is equipped with adequate plasticity-based constitutive models to generate a simplified micro-model approach. The elastic and plastic behavior of joints between bricks is simulated by using a surface-based cohesive response, while the Drucker Prager plasticity model is utilized to model the crushing of the brick under compression. The default concrete damage plasticity model and isotropic plasticity model are used to present the constitutive relations of concrete and reinforcing bars, respectively. By validating the simulation outcomes with experimental results, it is found that the proposed numerical approach can be used as an efficient alternative means to analyze the behavior and failure modes of a reinforced concrete frame with infilled walls.
