摘要

This study investigates the behavior of four-layer steel shear walls (4LSSWs) consisting of vertical trapezoidal double-layer corrugated sheets surrounded by flat sheets under cyclic loading in Abaqus software. Additionally, for comparison, flat SSWs (FSSWs), double-layer corrugated SSWs (DCSSWs), and single-layer CSSWs were examined. The results showed no pinching phenomenon in the hysteresis curve of s (4LSSWs); this system has a fatter hysteresis curve than the other samples. The average equivalent viscous damping of the 4LSSW, FSSW, CSSW, and DCSSW samples was 44.58, 33.21, 41.37, and 42.02%, respectively. This investigation also demonstrated that the strength of 4LSSWs is higher than that of the other samples. In terms of the maximum strength value, FSSW ranked second, whereas the single-layer CSSW exhibited the lowest lateral strength. Furthermore, unlike double- and single-layer CSSWs, the angle of the corrugated sheet had a negligible effect on the strength of the 4LSSW. Generally, the average equivalent viscous damping of all 4LSSW, single-layer CSSW, and DCSSW samples was 44.58%, 41.37%, and 42.02%, respectively.
