Cold-formed steel members are susceptible to instability phenomena, including local, distortional, and global buckling. Most of the existing literature assumes that cold-formed steel members are subjected to uniform compression. However, in actual joints within steel-framed structures, cold-formed steel members experience non-uniform stresses due to eccentricity. Therefore, in this study, we conducted stub column tests under eccentricity and performed analyses using the finite element method. The results confirmed that the influence of eccentricity led to the occurrence of the buckling mode different from the uniform stress state and ultimate resistance changing with the amount of eccentricity.
