交叉拱支网壳的稳定性参数分析

Parameter Analysis of Stability for Structures with Crossed Arch-supported Latticed Shell

分析了交叉拱支网壳这种典型杂交空间结构的整体稳定性。通过改变网壳矢跨比、拱刚度、活荷载分布和结构边界条件等参数,全面探讨了该结构的稳定性,并得到一些有规律的结论,可为相关工程设计提供参考。

Stability for structures with crossed arch-supported latticed shell, a kind of typical hybrid space structure, is analyzed. By means of changing the rise-span ratio of a latticed shell, the stiffness of the arch, the distribution of live load and boundary conditions and the stability behavior of the structure are investigated in detail. Some important rules are attained, which can provide references for related structural design.
