摘要:
阐述了轴心受压情况下典型套管构件的简化力学模型,选择利用合理的套管构件内核本构关系,用2个算例(内核圆钢管不同工况下的轴压承载力分析和网架结构应用套管构件的稳定计算分析)分析了外钢管对轴心受压内钢管的失稳控制效果.分析结果表明:套管构件作为失稳控制措施能够使得轴心受压钢构件失稳得到有效控制,可以应用于桁架、网架以及网壳等对受压钢构件失稳比较敏感的一类空间结构.最后提出了利用套管构件对轴心受压钢构件进行失稳控制研究中需要进一步解决的问题.
Abstract:
A simplified mechanical model of a typical axially loaded sleeved compression member(SCM)is introduced. Some reasonable constitutive relation curves of the inner steel tube are chosen for analyzing in two numerical examples. One is analysis on its axially loaded bearing capacity under different working conditions. The other is stability analysis of grid structure with SCM. The buckling control effect of the inner steel tube is evaluated with the outer steel tube applied in these conditions. The results show that SCM can effectively control the buckling of axial compression steel member. And it can be used in spatial structure which is sensitive to the buckling of compression steel member, such as truss structure, grid structure and reticulated shell structure. Finally some issues about further study of buckling control with SCM are put forward.
