Large-Scale Cyclic Testing of Steel-Plate Shear Walls with Coupling
The steel-plate shear wall with coupling (SPSW-WC) system is a natural extension of the conventional steel-plate shear wall (SPSW) seismic force–resisting system. The SPSW-WC configuration is created by linking a pair of SPSW piers together with coupling beams at the floor levels. Two half-scale, three-story specimens were tested using hybrid controls to simulate the bottom three stories of six-story prototype structures. The experimental SPSW-WC specimens demonstrated robust cyclic performance. Both specimens reached 4% lateral drift, the maximum displacement that could be imposed by the facility, with minimal strength degradation. Additionally, a large amount of energy was dissipated during each test, with over 20% equivalent viscous damping observed in the 4% drift cycles. The web plates, horizontal boundary elements, and coupling beams all exhibited ductile response through large inelastic deformations. The SPSW-WC configuration was shown to be a viable seismic lateral force resisting system for use in high seismic regions.
