Abstract: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.

Keywords:response spectrum; dense mode; earthquake effect; space structure
