Cold-formed steel (CFS) Shear wall has become popular in the construction industry because of some exceptional benefits like high strength to weight ratio, low maintenance, and high durability. Still, there is a crucial problem, particularly for promoting CFS structures in the seismic region, where many design elements stay open. The aim of this research is to analyze the lateral load capacities of shear walls used in residential buildings with CFS frames to overcome this problem. Five high-fidelity finite elements (FE) models for simulation of shear wall behavior with different types of sheathing materials, i.e., Fiber cement board, gypsum board as well as FE-CFS shear wall model without sheathing board, are presented in this paper. Shear walls were subjected to monotonic lateral load, and a comparative study of load-carrying capacities are presented. It was observed that the addition of sheathing to the CFS frame improves the shear resistance of the wall structure. Further study was carried out by simulating the shear wall models with varying the thickness of sheathing boards for observing its effect on the lateral load-carrying capacity. The main failure modes observed were screw pull-out, which caused sheathing material separation from the frame in some locations, and local buckling of studs. The results of this study (like various shear wall failure modes observed through Abaqus modeling) can be useful for practical considerations.
