The aim of this study is provided method on how to evaluate the hysteretic behavior of steel column subjected to combined variable axial force and cyclic flexure. For this purpose, the column experiments were performed under various complex loading paths. The numerical analysis of column under combination action of variable axial load and bending moment was carried out using constitutive material model proposed by Yamada et al. (2002). It was shown that predictions for global and local hysteretic behaviors were in excellent agreement with experimental results. On the basis of numerical analysis results, damage relationships between member and material could be evaluated, which is related to these under constant axial load and reversed bending moment.
