摘要
首先简要地就多点激励的模拟、分析方法等介绍了近年来国内外多点激励问题的研究现状，然后主要针对大跨度桥梁，侧重阐述了不同结构型式对多点激励的反应特征等方面已取得的一些研究成果和结论．最后就如何进一步展开该领域的研究进行了初步探讨．
This paper provides a summary of recent progress in the field of multiple-support seismic response of long span bridges. First, how to describe the spatial variability of earthquake motion is introduced. Second, methods of analysis are discussed. Then based on the existing research work, response characteristics of various long span bridge structures are investigated, focusing especially on three special types. Finally some open problems and research needs are predicted.
