采用三维地震理论和振型分解反应谱法，对目前两种常用的网格形式的双层圆柱面网壳分析了几十个具体算例，找出它的动力特性变化规律和主要影响参数，用回归分析方法建立基频近似计算公式，提出了地震反应主方向判别原则．双层圆柱面网壳的抗震性能研究@张锦虹@陈扬骤
Three-dimensional seismic theory and mode-decomposition response spectrum method are used to analyze dozens of concrete examples of the two commonly used grid-type double-layer cylindrical lattice shells, and to find out the dynamic characteristics and main parameters of its dynamic characteristics. The approximate calculation formula of the fundamental frequency is established by the regression analysis method, and the principle of the principal direction of the seismic response is proposed.
