| 摘 要： | 双层柱面网壳结构是一种新型空间网壳结构,近几年得到快速发展,相关理论也更加成熟.但是预应力双层柱面网壳的研究却不多,理论计算分析也不完善,尤其对其稳定性的研究更是少之又少.利用有限元法,考虑不同矢跨比、荷载分布及预应力水平对预应力双层柱面网壳稳定性的影响,并与对应的双层柱面网壳结构进行对比,分析预应力作用下网壳的稳定特性.

| Abstract: | The double-layer cylindrical latticed shell presents a new type of the spatial latticed shell which gets developed in recent years and the related theories are also getting much more mature. However, the study of the prestressed double-layer cylindrical latticed shell is few especially for its stability and the theoretical calculation and analysis are also imperfect. With finite element method this paper analyzes the effect on the stability of the prestressed doublelayer cylindrical latticed shell when considering different rise-span ratio, load distribution and prestress level,and the stability of the prestressed latticed shell by contrast with the corre- sponding double-layer cylindrical latticed shell. |
