中文摘要	The finite element analyses( FEAs) were performed using the general software ANSYS for the overall buckling behaviors of the 5 ultra-high strength steel welded I-seetion columns under the axial compression. The building procedure of the FEA model and the solution programs were introduced in detail. The method to simulate the initial geometric defects and the residual stresses in the cross-sections were proposed. The effectiveness of the performed FEA was verified by the comparison between the FEA results and the test results. The FEA also indicated that the residual stress only has little effect on the overall buckling resistance of the ultra-high strength steel columns.
