| 摘 要： | 本文利用ANSYS软件对某整体坍塌的40m大跨度球面网壳结构进行了静力验算和整体稳定性分析,对各种荷载工况下构件的强度、刚度、稳定性及结构整体的稳定性进行了验算分析,得出了该网壳结构破坏形式主要是整体失稳破坏,其整体稳定性系数不满足规范要求的结论,提醒设计人员应注重对大跨度球面网壳进行考虑初始缺陷的整体稳定性分析。 |

| Abstract: | This text make the static analysis and overall stability analysis of one 40m latticed shells by ANSYS. Cornt~nent＇s strength, stiffness, stability and the integral stability of the structure are analysed under the various load cases. According to the calculation, the conclusions that the whole buckling failure is the main form of the destruction, the integral stability coefficient does not meet specifications are drew. This reminds that we should focus on the for analysis of integral stability considering initial irapet.fection large-span spherical shell. |
| Keywords: | Latticed shells Static analysis Overall stability Initial imperfection |
