摘要
结合高振型动力效应特点及反应谱法基本原理,给出了具有密集振型分布特征的空间结构地震作用修正计算方法。同时,结合具体工程,验证该计算方法的有效性。为方便使用还给出了计算步骤。对从事大跨度空间结构设计的工程师和结构计算软件的开发人员具有借鉴意义。
Considering the high frequencies influence on structures and the basic principle of spectrum methods, the computation method upon space structures with the characteristic of dense mode distribution is put forward basing on Chinese code, and the accuracy of the method is verified through a project. To facilitate the application, the calculating procedure is given. The study is valuable for the engineer engaging in large space structures and the programmer developing structural computation software.
