【摘要】 本文就带肋方形底单层扁球网壳的稳定性能做了详细的分析探讨，得出了其肋与肋的位置、跨度、矢跨比、荷载、支座条件、网格数以及网格形式的关系，并与相应单层网壳做了比较。由此得出结论：加肋能不同程度地提高单层扁球网壳的稳定性能。更多还原

【Abstract】 This paper presents the results of the analysis on the stability of part rib strengthened single layer square based shallow globular reticulated shells under consideration of the influencing factors such as span,rise to span ratio,load distribution,supporting conditions,grid module number and grid module shape,by comparing with the single layer shell without being strengthened;it also draws a conclusion that part ribs can raise the single layer shells′ stability in varying degrees.更多还原
