摘要
比较了大跨空间结构在多维多点地震下的3种反应分析方法,阐明了大跨度空间结构中多维多点地震输入和考虑多向地震作用的必要性,同时介绍了隔震、各种快速算法在抗震中的应用。
This paper analyzes and compares three seismic response analysis methods for a large-span spatial structure under multi-dimensional and multi-point earthquake, illustrates the necessity of the multi-dimensional and multi-point excitations and the action directions of earthquake for the large-span spatial structure, and introduces the applications of the isolation and various fast algorithms in seismic engineering.
