Study on Performance Index Quantification of PRC Coupling Beam-Hybrid Coupled Shear Wall System

Abstract

PRC coupling beam-hybrid coupled shear wall system is a new structural system with plate-reinforced composite (PRC) coupling beam instead of concrete coupling beam in the traditional reinforced concrete coupled shear walls. There is a lack of systematic research on PRC coupling beam-hybrid coupled shear wall system at home and abroad. In this paper, the seismic performance levels of PRC coupling beams and shear walls were partitioned. Combined with the characteristics of PRC coupling beam-hybrid coupled shear wall system, the failure features at different performance levels are put forward. Meanwhile, story drift angle limitation for PRC coupling beam-hybrid coupled shear wall system under different performance levels is obtained. According to the using function and importance of PRC coupling beam-hybrid coupled shear wall system, the seismic performance target of which is given combined with different earthquake action levels.
