The capacity and different failure modes for the axially loaded single lipped cold-formed sigma column are discussed. The residual stress pattern and the average local/ distortion as well as overall imperfections measurements are determined. Comparison between the experimental, FE and design codes (DSM & AISI) is carried out.
