Cutting roll-formed steel C-section to stub columns will produce different extents of cross section distortion along the length and cause additional initial geometric imperfections. Considering material nonlinear, geometric nonlinear and initial geometric imperfections, the axial compressive bearing capacities and failure modes were analyzed with finite element method for cut stub columns with two kinds of C-section. The analysis results were compared with the compressive testing data of the cut stub columns, showing that the failure modes of the two flanges were obvious distortional mode, while those of the webs were local buckling failures. The geometric imperfections caused by cutting reduced the ultimate strength of the fixed-ended stub columns by 7%∼11%.
