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压构件稳定性研究现状的基础上,找出了高强钢稳定性设计方法存在的不足,结合数值积分方法和模型试验方法,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压构件稳定系数的计算公式,同时也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.
The emphases of application and investigation of the high strength steel are laid on stability of the axial compressed member.On the basis of analyzing the current research situation of the stability of the axial compressed member,the limitation of design methods for the stability of high strength steel were found.By means of numerical integration methods and model tests,the formulae which parameters include yield strength of material and slenderness ratio of member was put forward for calculation stability coefficient of the axial compressed member of the high strength steel,and some significant conclusions were arrived at.The research is significative for application and investigation of the high strength steel.
