Based on the finite element method, the typical layout and parameters were selected to establish the overall structure model of steel frame—cold-formed thin-walled steel composite wall and their influence on the mechanical properties and the economic steel amount was analyzed. The results show that the screw spacing, purlin section and purlin spacing have little effect on the lateral stiffness and the amount of steel used in the overall structure, while the width of wall opening has obvious effect. It is suggested that the screw spacing should be consistent with the relevant provisions in the cold-formed thin-walled steel structure specification, the purlin section should be selected relatively small according to the wall thickness and the purlin spacing should be properly amplified. The applicable height of this structure system is higher than that of pure cold-formed thin-wall steel structure system in ordinary residential buildings. The amount of steel used in this structure system is obviously less than that of pure steel frame structure system.
