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.
