摘　　要：综述了结构多分量地震作用研究的发展概况．在第（Ⅰ）部分中，主要综述了多分量地震动输入的有关问题．分别从多分量地震动的转动分量、随机模型及相关性的研究方面进行了讨论．在第（Ⅱ）部分中，主要综述了结构在多分量地震作用下的反应分析方法，包括多分量抗震分析的反应谱法、时程法和随机方法，最后讨论了结构多分量地震作用研究小存在的问题，对今后的研究方向提出了展望．The state-of-the-art of research on multi-components earthquake excitation to structures is summarized in this paper. In part I, the aspects for multi-components seismic input are discussed, which are mainly related to the research on rotational component of ground motion, random model and correlation of multiple seismic ground motions. In part n , the analysis methods for multi-components seismic excitation to structures are reviewed, which consist of the seismic response spectrum method, the time-history analysis method, and the random vibration method. Finally, the problems and prospects of the research are discussed, and the aspects for further research are recommended.
