摘　　要：大型的网壳结构具有受力合理、重量轻、造价低而且造型优美、形式新颖活泼等特点,成为近年来发展最快的结构形式之一。本文以某工程为例,使用ANSYS软件,结合时程分析法,对椭球形双层网壳结构进行动力分析,得到杆单元的轴力时程曲线。通过比较杆单元在不同方向的地震作用下的轴力时程曲线,分析网壳结构在地震作用下的内力规律,为今后的抗震分析设计提供依据。Large Reticulated Shell with many advantages such as ,reasonable force performance ,light weight ,low cost ,elegant ,and lively form ,which has becoming one of the fastest growing form of structure development in recent years .Taking a project as an example ,we combined with time history analysis mathod by using ANSYS software ,to do dynamic analysis for the Ellipsoidal double reticula‐ted shell ,and got a curve of axis force stem cell to time .The law of earthquake response excited by earthquake wave is gotten by comparing the elem axial force time curve course in different directions seismic action .This result will provide the benefit help for the type design .
