摘　　要：总结了近年来国内外学者对速度脉冲、竖向地震动和上下盘效应等近断层地震动特性的研究成果,综述了近断层地震作用下隔震结构动力响应的研究现状。对当前近断层隔震结构地震响应研究和抗震设计中存在的问题进行了简要分析,指出考虑近断层的速度脉冲效应、竖向地震动特性和地面运动不一致性以及结构P-Δ效应等因素影响,将成为隔震结构动力反应分析和结构抗震设计新的研究方向。In the present paper,research on the character of near -fault ground motions, including velocity pulse effect, vertical seismic ground motions and hanging wall effect, and its corresponding influence on base -isolated structures was reviewed and summarized. The existing problems so far were pointed out and work both in respect of response character and aseismatic design needed to be further investigated in the future was suggested, such as con- sidering the influence of velocity pulse, vertical seismic ground motions, inconsistency of ground motions and P - A effect.
