Abstract
Steel corrugated shear walls (SCSWs) are an alternative to ordinary steel plate shear walls (SPSWs) with flat infill plates. This paper deals with the shear resistance design of corrugated panels in SCSWs under monotonic loading. Based on the validated finite-element analysis (FEA), key parameters affecting the ultimate and postultimate strengths of corrugated shear panels were identified and the proper values were recommended. By introducing the normalized slenderness ratio, design formulas were established for the ultimate strength and residual strength of corrugated panels. Recommended corrugation profiles were tabulated for convenience of practical use to ensure high and stable shear resistance. It was found that, compared with the ultimate strength, variation of the residual strength against the normalized slenderness ratio is much more complicated, and the corrugation dimensions must be chosen properly according to the proposed design equations and recommendations to avoid unstable postbuckling behavior.
