为了探讨偏心基础滑移隔震结构在双向水平地震波输入下的结构地震反应，以一基础滑移隔震五层剪切型结构为例，采用SAP2000程序，通过改变结构构件的布置来改变结构质量中心的偏心距，分析在不同偏心距下结构的反应。结果表明，隔震层和上部结构的加速度随偏心距增加而减小，而结构的扭转效应和位移反应则随偏心距的增加明显增大。因此，在实际应用中应该控制结构的偏心距以保证隔震结构的隔震效果。

In order to study the seismic response of base -isolated building to bi -directional horizontal earth-quake , taking a five-layer shear structure with sliding base -isolation as an example , using SAP2000 program, the response was analyzed under different eccentricity by changing the arrangement of structure components to change the center of mass eccentricity .The results showed that the acceleration of isolation layer and the upper structure decreases with the increase of eccentricity , while the torsion effect and displacement response increase with the increase of eccentricity obviously .Therefore , the eccentricity of the structure should be limited to ensure the isolation effect of isolation structure in the practical application .
