［摘要］选择了一个特定地区的大型双层拱形网壳结构作为研究对象，采用有限元分析软件MIDAS/Gen8-26进行了安装全过程仿真分析。针对当地的风荷载特征，分析了该结构在安装过程中位移和应力的变化情况，通过对比有风和无风的分析结果，得到了风荷载对结构安装过程的影响，并设计了抗风措施。

Abstract:A large bilayer arch reticulated shell structure of a specific area was selected as the research object, and the whole process simulation analysis was carried out by using the finite element analysis software MIDAS/Gen8-26. According to the local wind load characteristics, the displacement and stress of the structure during the installation process are analyzed. By comparing the wind and windless analysis results, the influence of wind load on the structure installation process was obtained, and the wind resistance measures were designed. 

Keywords:bilayer arch reticulated shell; wind load; simulated analysis; wind-resistance design
