为更加深入研究空腹网壳结构的稳定性，取单种空腹扁网壳结构，在矢跨比、结构厚度、截面尺寸等不同参数变化下进行稳定分析研究。利用ANSYS有限元在先对单榀的空腹平面拱进行计算分析的基础上，进一步开展对空腹扁网壳结构的屈曲模态分析及非线性参数化屈曲分析，得出平面空腹拱和空腹扁网壳两种结构在不同参数的变化下对结构极限承载力的影响情况，并了解其稳定性能。

In order to research the stability of the vierendeel shell in depth on the vierendeel flat shell, this article has a stability analysis and research in the case of different parameters of span ratio, structure thickness and section size. On the basis of the computational analysis of single pin for plane vierendeel arch by the ANSYS FEM, we have carried out the further modal analysis and nonlinear parameter buckling analysis of the vierendeel fiat shell, and get the impact on the two structures of plane vierendeel arch and vierendeel flat shell when different parameters change. Then we understand its stable performance.
