Abstract:将点阵结构引入薄壁简壳结构的壁面构型中,构建双层蒙皮加筋柱壳结构.应用点阵结构的高比刚度、高比强度等优良力学性能,提高薄壁简壳结构的轴压极限承载
力.双层蒙皮网格加筋柱壳结构是在传统网格加筋结构的内侧增加一层蒙皮,使得该网格加筋结构的横截面为"工"字型,提高了该结构抗弯刚度,进而提高了结构
的轴压承载力.针对双层蒙皮网格加筋结构,本文开展了基于模态缺陷和基于单点凹陷的缺陷敏感性分析,对比分析双层蒙皮网格加筋结构与传统网格加筋结构的轴
压承载效率.结果显示双层蒙皮网格加筋结构较传统结构具有显著的高承载力优点.进一步,本文给出了考虑几何缺陷的轴压双层蒙皮加筋柱壳结构的优化设计,最
优设计有效地提高了结构折减因子,提高了结构抗缺陷能力.
