摘要:高强钢轴心压杆的稳定性是目前高强钢应用和研究的重点。在分析了目前高强钢轴心受压构件稳定性研究现状和高强钢稳定性设计方法存在的不足的基础上，结合大型有限元分析软件ANSYS的稳定分析功能及模型试验方法，对高强钢轴压心受构件的整体稳定性进行了研究，提出了以材料屈服强度和构件长细比为参数计算高强钢轴心受压构件稳定系数的计算公式，得到了一些有意义的结论，对今后高强钢的应用和研究具有重要的意义。

Abstract: One of the research emphases of application and investigation of high strength steel are laid on stability of axial compressed member. After analyzing stability of high strength steel and limitations of design method for stability of high strength steel analyzed, combined with the function of stability analysis of large finite element analysis software ANSYS and model test, stability for axial compressed members of high strength steel are researched, and formulae which parameter includes yield strength of material and slenderness ratio of member is put forward for calculation stability coefficient of axial compressed member of high strength steel. Some important conclusions are arrived at. The research is significant for application and investigation of high strength steel in future.
