Abstract

Double-corrugated steel shear walls (DCSSWs), made of two connected trapezoidal corrugated plates, were developed to address the limitations of single-CSSWs. In recent years, flat-corrugated steel shear walls (FCSSWs) built from flat and corrugated plates have been introduced to benefit from the advantages of flat and corrugated steel plates. In this exploration, the lateral behavior of the DCSSWs and FCSSWs with different corrugation angles and infill plate thicknesses is investigated under cyclic lateral loading in ABAQUS software. The outcomes indicate that FCSSWs exhibit superior performance compared to DCSSWs due to the interaction effect in the flat and corrugated plates. The maximum strength of the FCSSWs is increased by at least 1.7% and a maximum of 12.0% compared to the DCSSWs. Additionally, energy absorption in DCSSWs is not significantly different from that in FCSSWs, with variations ranging from 0.7% to 4.5%. In some samples, flat-corrugated walls absorb more energy, while in others, double-corrugated walls do. The flat-corrugated system uses 3.4%, 6.8%, and 12.04% less steel at corrugation angles of 30°, 45°, and 60°, respectively, and shows higher maximum strength, making it more economical than the double-corrugated system. The outcomes displayed that with the increase in plate thickness, the equivalent viscous damping increases.
