摘要
有计划地对１００例四边铰支单层柱面网壳和３６例纵边铰支单层柱面网壳进行了荷载－位移全过程分析，求得了它们的极限承载力。选取了不同的矢宽比、荷载形式等参数。考虑了６种长跨比，系统讨论了长跨比对单层柱面网壳稳定性的影响以及其它参数对柱面网壳稳定性影响规律和长跨比的相关性，较好地掌握了单层柱面网壳稳定性的规律。
Aimed at 100 Single-Layer Lattice Vaults supported along the boundary and 36 vaults supported along two longitudinal edges,the load-displacement complete-process analyses are carried out and their limit loads are acquired with considering 6 kinds of length-span ratios,and with different raise-span ratios and load modes As a result,a practical formula for analysis of the stability of Single-Layer Lattice Vaults is suggested which can be used as reference for engineering design
