摘要
高强钢轴心压杆的受力性能包括强度和稳定,其性能是目前高强钢应用和研究的重点。在分析高强钢稳定性设计方法存在不足的基础上,结合数值积分方法、有限元程序ANSYS数值模拟方法及模型试验方法,对高强钢轴心压杆构件的稳定性进行研究,提出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。计算结果表明,数值积分法和ANSYS数值模拟法计算程序原理正确、程序可靠、结果可信,同时也得到一些有意义的结论,对今后军用桥梁装备的研制开发、现行《军用桥梁设计准则》的修改制定和军用桥梁结构相关设计方法的改进完善将具有重要意义。
The research emphases of application and investigation of high strength steel are laid on mechanical property including strength and stability of axially compressed member. After limitations of design method for overall stability of high strength steel analyzed, by means of numerical integration method, ANSYS numerical simulation method and model test, overall stability for axially compressed members of high strength steel are researched, and formulae whose parameter includes yield strength of material and slenderness ratio of member is put forward for calculation stability coefficient of axially compressed member of high strength steel. It is observed that principle veracity, program reliability and result reliability of the numerical integration method and the ANSYS numerical simulation method for overall stability of axially compressed members of high strength steel are proved, and some significative conclusions are obtained . The research is significative for development of military bridge equipments, modification of the current Design Criterions for Military Bridge and improvement of correlative design methods for military bridge structure in future.
