摘要:

首先简要地说明了大跨度结构在抗震分析中的特点以及目前常用的计算大跨度结构多点激励地震反应的三种方法，继而详细地论述了近年来大跨度结构多点地震激励反应谱分析方法的国内外研究现状，最后对该领域的发展方向以及进一步深入研究时所需要注意的问题进行了初步的探讨。

Abstract:

The features of seismic analysis of long-span structures and the three methods which are commonly used in analyzing the seismic response of long-span structures under multi-support excitations are briefly stated, and then the research developments of multi-support response spectrum method at home and abroad are presented in detail. Finally, some problems needing further investigations are proposed.
