摘要

Cold-formed steel (CFS) shear walls using corrugated steel sheathing is a newly proposed lateral resisting system from recent research. In this paper, Finite element models of cold-formed steel framed shear walls sheathed by corrugated steel sheets were created in Abaqus software. The validity of the numerical model was verified based on previous test results. Agreement of the FEA results and test results indicated that the proposed numerical model was able to accurately predict the shear resistance of cold-formed steel shear walls with corrugated steel sheathing. A series of parametric analysis were then conducted, including the thickness of framing members, cross section of stud members, yield strength of frame members, stud spacing, and the influence of gravity load. The detailed modeling information, relevant parametric analysis results and recommendations for practical application of this type of shear resisting system are presented in this paper.
