Study on the Analysis Model of the Self-Centering Wall

Abstract

The self-centering wall including both prestressed tendons and dampers is proposed in this paper, and the corresponding general finite element numerical analysis model, simplified numerical analysis model and theoretical analysis model were established respectively, focusing on how to simulate the prestressed tendons, dampers and the horizontal connection between the wall and the foundation. The numerical simulations of the self-centering wall subjected to reversal loading were performed using the above two numerical analysis models, and the results were compared to those obtained from theoretical analysis. It is indicated that the hysteresis curve of the self-centering wall under reversal loading exhibits flag shape and no residual displacement exists after the wall is unloaded completely. The numerical analysis results match well with those from theoretical analysis, which shows the two numerical analysis models proposed in this paper can be well used to capture the mechanical behavior of the self-centering wall.
