| 摘 要： | 利用有限元程序ANSYS对某单层球面网壳进行了静力稳定性分析,得出了其在集中力、半跨均布荷载和全跨均布荷载下屈曲的全过程曲线,并进行了分析,分析结果表明:网壳在集中力作用下屈曲的变形最小;不对称荷载作用对网壳稳定承载力影响较大。

| Abstract: | The static stability of single layer spherical lattice shell was analyzed with finite element program ANSYS,the whole process curve under concentrated force,half-span uniform load and whole span uniform load bending was obtained and analyzed.The analysis result indicated that the reticulated shell bending deformation was small under concentrated force,the asymmetric load effect had large influences on reticulated shell stability bearing capacity. |
