Structural performance of the orthogonal double corrugated steel shear walls under lateral cyclic loading
摘要
Orthogonal double corrugated steel shear walls (ODCSSWs) entailing horizontal and vertical trapezoidal corrugated plates have been introduced recently. This article explored the hysteresis behavior of ODCSSWs compared to conventional single-corrugated steel shear walls (CSSWs) and double-corrugated steel shear walls (DCSSWs) with horizontal and vertical directions under cyclic loads in software ABAQUS. The outcomes revealed that ODCSSWs have a plump and stable hysteresis curve. It was found that ODCSSWs, unlike DCSSWs and CSSWs, did not show any decrease in lateral strength before the ultimate drift. The findings showed that the maximum strength of ODCSSWs is at least 6.5% and a maximum of 12.4% higher than that of conventional double corrugated walls. Also, the increase in maximum strength in ODCSSWs compared to CSSWs varies between 10.6% and 16.2%. The increase in energy absorption of ODCSSWs compared to conventional DCSSWs walls is between 8.9% and 23.7%. The finidngs indicated that the difference between the maximum strength of the ODCSSWs and DCSSWs is decreased by increasing thickness of infill double-corrugated plates. The obtained result also showed that the initial stiffness of ODCSSWs, DCSSWs, and CSSWs are very close.
