中文摘要: 摘要:波形腹板金属支架结构由于腹板波折后较平腹板构件的受力性能得到了很大的改善。本文以马蹄形断面波形腹板支架形式为例,采用正交设计方法建立了静水压力下支架结构的腹板厚度、腹板高度、翼缘宽度和厚度等截面参数如与支架结构一阶弹性整体屈曲荷载之间的函数关系;并在此基础上分析马蹄形断面各半径变化对整体屈曲荷载的影响,进而推导出支架结构一阶弹性整体屈曲荷载的计算公式。

Abstract:Abstract:The loading behaviors of the metal supporting structure with corrugated webs are greatly improved by the corrugation in the webs compared with that of the members with plain webs. The U-shaped supporting structure with corrugated webs is studied. The function relation between the structural section parameters such as the height and thickness of the webs, the width and height of the flanges, and the first-order elastic overall buckling load of the supporting structure under hydrostatic pressure is established by using orthogonal design method. Furthermore, the relationship between the section radius of the U-shaped supporting structure and the overall buckling load are also studied. Based on these, the formula of first-order elastic overall buckling load of the supporting structure is derived herein.
