An elastic - plastic and geometrically nonlinear finite element method is developed to analyze ultimate strength of h - shape steel columns under axial compressive loading . initial imperfections including residual stress due to hot - rolled and initial overall deflections of columns are considered . an experiment study of 21 h - shape steel columns with slenderness parameter of ranging from 40 to 120 is conducted to verify the theory results 本文通过弹塑性和几何非线性的有限单元法理论分析，在长细比范围在40 ? 120的21根国产h型钢轴心受压柱的承载力试验中进一步证实了这一理论的合理性和有效性。
