摘要

This paper shows studies on essentially experimental basis of columns strength in thin-walled steel plate (cold-formed profile), submitted to centred compression. Special attention is given to instability phenomena, including local-global buckling interaction for the case of cold-formed "S" profiles. The research was based on a large series of tests that were performed for stub, intermediate and slender columns and incorporated the analysis of some buckling curves propositions. Reliability prediction of the proposed buckling curve was verified for different groups of experimental results, including local-flexural, distorsional-flexural and local-torsional flexural buckling interaction.
