Investigation of the Behavior of Steel Plate Shear Walls Considering Double Corrugated Low-Yield-Point Steel Infill Plate

Abstract During the last three decades, interest in application of steel shear walls has increased worldwide. Steel are used as stiffened and unstiffened walls. One main shortcomings plate wall (SPSW) is infill buckling mainly under lateral wind seismic loads. useful solutions to prevent use with corrugated plates. In this research, behavior a consisting two plates was investigated material cases conventional ASTM A36 low-yield-point (LYP) steel. The low yield strength improves performance system. study, effect corrugation angle aspect ratio were investigated. results showed that on structural parameters LYP greater than By increasing from 30° 60°, elastic stiffness decreased about 24 36%, respectively, response modification factor (R u ) by 56%. lower ultimate energy absorption. Investigating wall.
