アブストラクト
The influences of initial imperfections on the performance of square steel tubular columns under axial force with one end bending moment were investigated by means of FEM in our previous study. In reality, columns of steel structures are subjected to axial load with bending moment close to antisymmetric. Therefore, it is necessary to clarify the performance and the elasto-plastic behavior under such load conditions. Firstly, the influence of initial imperfection on the performance is investigated in this study, individually. Secondly, the influence of combined initial imperfections on the performance and on the elasto-plastic behavior are investigated; comparison between the experimental results are also shown.
