Distortional buckling may occur for cold-formed lipped C-section member subject to compression. In this paper, we carried out compression tests of cold-formed lipped C-section members with length where distortional buckling occurs in elastic buckling analysis and their buckling behavior is investigated. As the test results, local buckling of each component plate or flexural torsional buckling first occurred. For the lipped section which is fabricated according to the specification, lip/ flange junction deformed like distortional mode after web local buckling. In this tests, distortional buckling mode has little effect on the strength and the deformation behavior.
