某高层建筑顶部异型网架的结构抗震分析和设计
Earthquake Resistant Analysis and Design of Space Truss Connected Arches on the Top of a Highrise Building
【摘要】 本文结合工程实例 ,对位于高层建筑顶部装饰用异型网架的结构设计和地震反应进行了分析。在应用了常用的简化方法和抗震新规范推荐的楼面反应谱法进行了抗震设计后 ,应用振型分解反应谱法和楼面反应谱法进行了抗震验算 ,比较了两种方法的安全性和准确性 ,讨论了此类异型网架的自振特性、受力特点以及抗震性能 ,并给出一些设计上的建议和有益的结论
【Abstract】 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 and floor spectra method which is recommended by new code. The safety of the design is checked by use of the mode analysis response spectrum method. Some dynamic properties are discussed as well. Furthermore, conclusions are drawn and design suggestions are put forward.
