近断层地震动作用下工程结构地震响应的研究进展

Progress of Research on Structures Seismic Responses under Near-fault Ground Motions

介绍和概括了近年来国内外学者对近断层地震动作用下工程结构的地震响应问题的研究成果,以及近断层地震动作用下建筑结构、桥梁结构和地下结构动力响应的研究现状,并对当前近断层工程结构地震响应的相关研究进行探讨和展望。由于结构形式、受力荷载等不同,各类结构的地震响应也是不同的,但总体来说,工程结构对近断层地震动的响应是显著增大的。现阶段,近断层地震动作用下建筑结构及桥梁结构地震响应问题的研究工作开展的比较多,对于地下工程的研究相对较少,未来应着重关注对此方面的研究。

This paper presented the research achievements of the seismic responses of both engineer structures and the structures, bridges, as well as underground structures under near-fault ground motions made by domestic and foreign scholars in recent years. Besides, present and future researches on the engineer structures seismic responses were also discussed. The seismic responses of structures vary with the structure form and the stress load, but generally the response of structures to near-fault ground motions is prominently increasing. At present, despite more researches on the seismic responses of structures and bridges under near-fault ground motions, less has been done on the underground structures. Therefore, the latter should be brought into focus in future researches.
