摘要
本文基于弹性薄膜理论,对大型人防工程中的常用结构—球面扁壳结构进行内力分析,并对影响球面扁壳受力特性的壳体板厚、跨度、环梁位置等因素进行对比研究,进行结构优化设计。
Large spherical shells are widely used in engineering of people's air defence.By means of the approximate calculation method for elastic shells, the influence of thinkness' span’ and support of shells are analyzed in this paper.
