Seismic Performance Control of Tall Buildings Using a Novel Self-Centering Shear Wall System

Abstract

The reinforced concrete (RC) shear wall system is widely used as a lateral force resisting system in high-rise buildings. Nevertheless, the shear wall components of the system are vulnerable to destructive earthquakes, and the damage of shear wall components is a major hindrance for the seismic resilience of high-rise buildings. Therefore, a novel self-centering repairable (SCR) shear wall system is introduced in this study. Compared with the conventional RC shear wall system, the proposed SCR shear wall system exhibits good self-centering capability, and the energy dissipation element can be replaced easily after an earthquake. First, the configuration of the SCR shear wall is presented. Next, the design criteria used to achieve good self-centering and energy dissipation are discussed, and the finite element model used to simulate the SCR shear wall is presented. Finally, case studies are performed, and the numerical results indicate that the proposed SCR shear wall system exhibits better self-centering performance than the RC shear wall benchmark model. The outcomes of this study are expected to provide a useful reference for future experimental studies and practical applications of the presented SCR shear wall systems.
