摘要
矢跨比对单层球面网壳结构的刚度、整体稳定性及失稳区域有很大影响。本文在考虑杆件屈曲的基础上,通过对比四种不同矢跨比的单层球面网壳结构的极限荷载、失稳区域,分析了矢跨比对考虑杆件屈曲的单层球面网壳结构整体稳定性的影响。
Rise-span ratio has a great influence on single-layer lattice dome stiffness,the overall stability and instability regions. This paper compares the maximum loads under four different rise-span ratios of single-layer lattice dome,and the instability regions,and it analyzes the effect on the stability of the lattice dome as a whole.
