[摘要] 采用Ⅳ级场地天津波对某民居的砖混结构采用SBS隔震垫的效应进行了动力有限元分析，SBS隔震垫简化为弹簧和阻尼。通过分析发现，设置隔震垫后结构的周期增加、加速度减小、位移增大，设置SBS改性沥青隔震垫后对建筑具有较好的隔震效果，可在农村建筑中适当推广应用。

Abstract: Based on the dynamic finite element method,using the Tianjm seisnuc wave suitable forWtype field, the resisting effects of SBS material on some masonry buildings were analyzed. SBS material was simplified as spring and dashpot. The analysis results show that the period of the structure is enlarged, the acceleration decreases and the displacement increases when the resisting pat is used. So the SBS material can be applied in the village buildings for its good resisting seismic.
