Seismic resilience assessment and retrofit of the reinforced concrete frame shear wall building

Shuo Jia, Jia-Ming Huang and Dong-Jie Zhan

Abstract

This study concentrates on the seismic resilience assessment and reinforcement schemes of the RC frame shear wall building. Firstly, the theory of the GB/T 38591-2020 is introduced and the comparison among the international commonly used methods is conducted. Secondly, the fragility analysis and seismic resilience assessment of the RC frame shear wall building are performed, in which the resilience indicators (restoration cost, repair time and casualties) are elaborately analyzed. Finally, the retrofit schemes of the viscous damper, SMA brace and the hybrid of the two are proposed according to the seismic resilience weakness of the building, and the comparison of the original building and retrofit schemes is conducted. This study aims to help to identify the weak links of the existing RC frame shear wall building and formulate effective reinforcement schemes to improve the seismic resilience, which can provide theoretical reference for the retrofit of the RC frame shear wall building.
