Abstract
In response to the demand for resilient structures, a variety of innovative structural solutions have been recently introduced to reduce residual deformations and expedite the repair of structures subjected to earthquakes. This paper discusses the seismic performance of a self-centering lateral load-resisting system developed with the intent of diminishing earthquake-induced damage and residual deformations. The proposed solution is composed of a reinforced concrete (RC) shear wall coupled to two steel side columns with coupling beams featuring a friction-damped selfcentering mechanism. The intended system is referred as Self-Centering Hybrid Coupled Wall (SC-HCW). The applied self-centering mechanism is aimed at reducing earthquake-induced residual deformations. Limited residual deformations facilitate the repair of SC-HWs after severe earthquakes, which improves the seismic resilience of the structure. The seismic performance of a SC-HCW is examined and compared with that of a conventional hybrid coupled wall (HCW). Nonlinear static and Incremental Dynamic Analyses (IDAs) are conducted on these archetypes. The outcomes elaborate the efficiency of the SC-HCW in minimizing earthquake-induced residual deformations.
