摘要
在非线性分析的基础上,基于单层网壳结构的失稳机理,根据作者提出的失稳区域跟踪与判别方法,研究了两种不同形式的单层网壳在不同矢跨比时失稳区域的分布规律,以及失稳之前的弹性变形与失稳区域之间的关系。本文的结论对于网壳结构的稳定性能研究和应用有实际意义。
Based on the principle of instability, for two types of latticed dome, the effect of rise-span ratios on the instability region is studied by the methods of tracing and distinguishing methods. And the relation between the elastic displacement and the instability region is discussed. The conclusions are meaningful to research and practice on the stability behavior of latticed domes.
