摘要
采用非线性有限元分析方法,从大规模的几何参数分析入手,研究K8型单层椭球面网壳结构的静力稳定性能,包括短向跨度、矢跨比、杆件截面尺寸等参数与结构极限承载力的关系,并针对研究工作进行总结,得出一些有参考价值的结论。
Based on nonlinear finite element method, the static stability properties of K8-elli psoid reticulated shells with large-scale geometric parameters are analysed, in clud ing analyzing the relationship between the ultimate bearing capacity and the short span, rise-to-span, sizes of member sections, etc. Moreover, the thesis summarizes the r esearch and draws referential conclusions.
