Abstract:A type of practicable frame-rocking wall structure was proposed with the concept of replaceable member. According to the experimental study, four kinds of finite element (FE) models with different joint types were performed for simulating frame-rocking wall structure. The FE results show that the rigid joint should be adopted between ductility connectors and rocking wall or frame, while the rubber and shear keys between rocking wall and base can be simplified into hinge joint. Parametric analysis show that, as the increasing of the diameter of ductility connector and the thickness of rocking wall, inter-storey drifts of frame-rocking wall structure become more uniformly distributed, which leads to the increase of bearing capacity of the structure but the increasing rate becomes slower. The reasonable thickness of rocking wall should be determined according to the seismic demand, then the diameter and configuration of ductility connector can be optimized as presented in the paper.
