摘要

The current paper investigates the lateral performance of four-layer steel shear walls (SSW) encompassing embedded trapezoidal double-corrugated plates surrounded by flat steel plates. To this end, a one-story and single-span steel frame infilled with four-layer flat-corrugated steel plates, called flat-corrugated steel shear walls (FCSSWs), has been reviewed under lateral loading in the finite element ABAQUS software. Moreover, the lateral performance of flat SSWs (FSSWs), ordinary corrugated steel shear walls (CSSWs), and double-corrugated steel shear walls (DCSSWs) is investigated for comparison. Plate thickness and corrugation angle of the corrugated plates are two parameters. The findings showed that the FCSSWs demonstrate greater maximum strength, energy dissipation, and initial stiffness than other steel shear walls. The difference between the maximum strength of the FCSSWs and FSSWs varies between 6.1% and 13.3%. Also, the initial stiffness of the FCSSWs is at least 16.9% and a maximum of 47.7% more than that of FSSWs. Also, the maximum difference in the highest strength and initial stiffness of FCSSWs with DCSSWs is 16.3% and 12.6%, respectively. The findings showed that FCSSWs have shown increasing load-bearing capacity until the maximum allowable drift angle. CSSWs and DCSSWs may experience strength loss after plate buckling before the ultimate state.
