Abstract
Recent researches have proved cold-formed steel shear wall with corrugated steel sheathing a promising lateral force resisting system for buildings 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 recent research results on the new shear wall system including experimental and finite element analysis on shear strength and collapse probability analysis on seismic performance. Recommended shear resistance of the corrugated steel sheathing shear walls under wind load and seismic load was given in tabular form. A closed-form approach for calculating the story drift was developed. A set of seismic performance factors were proposed based on a compressive incremental dynamic analysis on six building archetypes.
