| 摘 要： | 以某低矢跨比的单层柱面网壳分析与设计为例,分析该网壳在各种荷载作用下的受力特点;讨论网壳支承刚度对网壳的受力影响;介绍网壳的设计和节点构造方法;并着重研究网壳的整体稳定性。得出：低矢跨比单层柱面网壳的整体稳定对支承刚度和初始几何缺陷较敏感;考虑塑性影响后,低矢跨比柱面网壳的稳定承载力相对弹性稳定承载力有大幅度降低;不同...

| Abstract: | By an example of analyse and design of one single layer cylindrical lattice shell with low rise-span ratio,mechanical characteristic of the shell was analyzed;the effect of support stiffness on the shell was discussed;the method of structure of shell joint and design of shell were introduced;especially the global stability was studied.It was concluded that single layer cylindrical lattice shell with low rise-span ratio was sensitive to stiffness of support and initial geometrical imperfections;and if plastic is considered,the critical load of the shell will be reduced greatly by contrast with elastic critical load;stiffness of support has different effect on the shell in different load cases. |
