Performance of cold-formed steel shear walls with single and double sided steel sheet sheathing subjected to cyclic loading

In high risk seismic regions, designers of structures with cold-formed members may tend to employ shear walls with steel sheathing to provide a higher shear capacity. This paper presents an experimental investigation into cold-formed steel shear walls with steel sheathing in one sideand both sides with different failure modes. Adding a steel sheathing on the second side increases the shear strength and stiffness of the walls. Shear strength improvement ratio, ductility ratio, and energy dissipation for walls with frame connection failure mode were higher thanwalls with chord stud failure mode
