摘要
结合工程实例，对位于高层建筑顶部装饰用异型钢架的结构设计与地震反应进行了分析。在应用简化方法估算的基础上，对该结构进行了多遇地震和罕遇地震下的反应谱和时程分析，评估了两种方法的安全度和准确性，探讨了此类异型网格结构的自振特性、受力特点以及抗震性能，并得到一些有益的结论供今后设计参考。
Earthquake responses of space truss connected arches as an engineering project lying on the top of a highrise building are analyzed in this paper. The seismic design of the structure is carried out by a simplified method, reaction spectrum analysis and time-history analysis of the structure under frequently occurred earthquake and scarcely occurred earthquake were carried out. The safety of the design is checked by use of the mode analysis response spectrum method. Some dynamic properties as well. Furthermore, conclusions are drawn and design suggestions are put forward.
