In order to investigate the shear resistance of cold-formed thin-walled steel skeleton wall under monotonic load, the finite element analysis of six walls was carried out to obtain the shear capacity of different walls and reveal the wrecking mode of the wall. The results show that the arrangement of rigid cross brace and rigid diagonal brace in the wall can significantly improve the shear resistance of the wall, the vertical continuous splay layout with two spans has the largest lifting range.
