Lateral strength and deflection of cold-formed steel shear walls using corrugated sheathing

Recent research has proven that cold-formed steel shear wall with corrugated steel sheathing is a promising lateral force resisting system in high wind and seismic zones. Extensive experimental investigations, including monotonic and cyclic tests on cold-formed steel shear walls with corrugated steel sheathing, were recently completed at University of North Texas. This paper summarizes previous and newly conducted tests and presents finite element analyses in order to establish a set of nominal shear strengths for the corrugated steel sheathed shear walls. In addition, a design method for determining the deflection of the corrugated steel sheathed shear walls under in-plane lateral loading was proposed based on the experimental results and nonlinear regression analyses. The deflections obtained from the proposed design equation were compared with the test deflections and good agreement was obtained.
