| Abstract: | Earthquakes occur in China frequently, and many are in the countryside or towns. Now there are many brick-and-concrete composite constructions or brick-and-timber constructions in the countryside and the towns, and they will still be major styles in future. So, it is necessary for these buildings to study seismic response. Sand cushion between foundation and soil can reduce the calamities caused by earthquakes. Sand cushion at input different peak value results different seismic response. The calculations of sand cushion can prove it. |

| Keywords: | sand cushion input wave response spectrum acceleration ratio |
