ABSTRACT
Concrete coupled wall is the outstanding seismic resisting system for mid to high-rise building structures. In this system, the link beam provides coupling action between the beam and the adjacent wall panel, which increases the lateral stiffness and reduces the footprint of the seismic resisting system. However, once the link beam is damaged due to a severe earthquake, it is difficult, costly, and time-consuming to repair. To deal with this issue, the Resilient Slip Friction Joint (RSFJ) is used to couple the wall limb in this study. RSFJ is a novel seismic technology which can satisfy the “life safety” and “immediate occupancy” criteria post-earthquake. An eight-storey reinforced concrete building is designed using the forced-based design method, and its seismic performance is evaluated by non-linear static pushover and nonlinear dynamic time-history simulations. The results showed that this system can provide a high level of structural ductility while providing fully self-centring behaviour.
