河南省体育场罩棚采用了变厚度双层扁网壳结构形式，长度２７０ｍ，最大悬挑５５ｍ。本文结合实际工程，采用有限元非线性分析理论对网壳结构的稳定性进行了全过程跟踪分析，分别讨论了网壳结构在有无初始安装偏差影响下的稳定性质。并对网壳结构进行动力分析，研究了结构的自振特性，然后进一步利用振型分解反应谱法，分析了竖向地震作用下，网壳结构的地震内力系数分布情况。
Henan Stadium shed shed with a variable thickness double flat reticulated shell structure, length 270m, the maximum overhang 55m. Based on the actual project, the whole process of the stability of reticulated shell is tracked and analyzed by using the finite element nonlinear analysis theory. The stability of reticulated shell under the influence of initial installation deviation is discussed. The dynamic analysis of the reticulated shell structure is carried out. The natural vibration characteristics of the reticulated shell structure are studied, and then the mode shape decomposition response spectrum method is used to analyze the distribution of the seismic internal force coefficient of the reticulated shell structure under the action of vertical earthquake.
