Abstract

The paper presents a test program on cold-formed steel lipped channel columns with geometries (cross-section dimensions and lengths) selected to ensure that they undergo interaction between local, distortional and global (flexural-torsional) buckling modes. The columns were compressed between fixed-ended conditions. The column ultimate loads, failure modes and load-axial shortening equilibrium path are reported.The test results obtained from this study provide clear experimental evidence of column interactive failures involving local, distortional and flexural-torsional deformations. Moreover, these test results also provide useful information for development of design rules aimed at predicting the ultimate strength of columns experiencing the triple interaction under consideration.
