| 摘 要： | 主要介绍了网壳结构的设计，包括结构体系的选取、结构分析方法、地震作用和稳定验算，着重对结构进行了脉动风振响应验算。通过分析得出在风压较大的地区，风荷载往往是网壳结构的控制荷载，因此在设计中必须要科学地考虑风的动力作用，对结构进行风振响应验算。

| Abstract: | This paper presents the design of a latticed shell, including the selection of structural system,method of structural analysis,checking computation of earthquake interaction and stability,especially focusing on the checking computation of fluctuating wind response.Through the analysis,it is obtained the wind load is often the control load in the area where the wind pressure is very large,therefore,the dynamic interaction of wind must be scientifically considered,and the checking computation of wind response must be carried out. |
