摘要
文章针对3种不同的活荷载"半跨"分布形式,得出了不同的稳定承载能力系数,考察了几何非线性、材料非线性对其稳定承载能力的影响。通过比较分析,找出了椭球面网壳最不利的活荷载分布形式,对实际工程设计工作有重要的指导意义。
The paper not only obtain different load-carrying capacity coefficient of the shell under different ＂half-span-load distribute＂ form,but also discuss how geometric nonlinearity and material nonlinearity influence the stability bearing capacity of ellipsoid reticulated shell.By comparison and analysis,the most dangerous form of ＂half-span load distribute＂ is found,and the result is of great significance to the design of practical project.
