Cyclic behavior of sandwich steel plate shear wall with embedded corrugated plate.

The sandwich structure has superior properties. To explore the application of sandwich structures in steel plate shear walls, this study presents a sandwich steel plate shear wall with embedded corrugated plate (ECSSW). The proposed wall is composed of two flat plates and a corrugated plate embedded between them. The flat and corrugated plates are joined by connectors. To study the cyclic behavior of the ECSSW, a quasi-static test and a numerical simulation of two specimens were conducted. In addition, a parametric assessment was conducted on the ECSSW with different connector horizontal spacings and strengths. The results showed that the ECSSW provides satisfactory seismic performance, does not produce significant noise, and can effectively delay the occurrence and development of infill plate buckling. With a small-wavelength embedded corrugated plate, the ECSSW can increase the yield load and yield displacement. The ECSSW with a large-wavelength embedded corrugated plate can reduce stiffness degradation and increase ductility and energy dissipation. When the strength of the connector is low, its horizontal spacing has minimal effect on the cyclic behavior of the ECSSW. The strength of the connector significantly affects the out-of-plane deformation of the ECSSW. • Application of sandwich structures in realm of steel-plate shear walls was explored. • A sandwich steel plate shear wall with embedded corrugated plate was proposed. • Seismic performance of the proposed shear wall was studied. • The proposed shear wall has three ductile fuses, namely flat plate, embedded corrugated plate, and frame. • Strength of the connectors significantly affects the proposed shear wall out-of-plane deformation.
