| Abstract: | The FEM model of two-way tapered eccentrically loaded column which consider the interactive buckling is built for the large-deflection and elastic-plastic analysis.In order to simulate the practical situation,the initial geometric imperfection and the residual stresses are brought in the model.The influence of the geometric parameters and residual stress to the in-plane stability carrying capacity is researched. |

| Keywords: | tapered I-shaped column interactive buckling in-plane stability |
