Corrugated steel sheet-sheathed cold-formed steel （CFS） shear walls are a new type of lateral force-resisting system. They have attracted extensive attention in recent years due to their high shear capacity and non-flammability. At present the shear capacity of such shear walls is mainly determined through experiments. There is limited variety in sheathing profiles and a lack of theoretical basis. To establish a design method for the shear capacity of corrugated steel sheet-sheathed shear walls， the shear capacity of shear walls was approximated by that of the sheathing instead. A total of 220 finite element models were developed to investigate the shear buckling load of corrugated steel sheets， and an eigenvalue buckling analysis was conducted. By considering both the elastic buckling strength and post-buckling strength of corrugated steel sheets， a calculation method for the shear capacity of corrugated steel sheet-sheathed shear walls was established. This method features a simple formulation and high computational accuracy， providing effective predictions for the shear capacity of walls sheathed with corrugated sheets having a rib height of approximately 15 mm.
