Abstract: Two kinds of roll-formed steel C-sections were taken as the research object. Stub columns were cut from the middle of long members. The cross section distortion and geometric imperfections along the length of the cut stub columns were measured. Measurement results showed that there was obvious cross section distortion in the cut stub columns after cutting, resulting in the large additional initial geometric imperfections along the length, which would affect the axial compressive ultimate strength and the failure modes of the cut stub columns.
