| Abstract: | In view of the wide application of large sized steel tubes in various structures, the performance of steel tube under the axial force is analyzed by nonlinear finite element in this paper. The influence of several factors on carrying capacity is taken into account. The influenced direction of these factors on ultimate carrying capacity is acquired and the basis is provided for the future analysis by the selected example. |
