Summary:For validation on effectiveness of soilbag cushion used as seismic isolation in low-rise building engineering in the urban and rural areas, a real building built with soilbags isolation cushion layer was constructed. Then, a large-scale in-situ test was performed on the building. The experimental results show that soilbags cushion structure has good seismic isolation performance. Also, the advantages of low cost and a simple construction procedure make it particularly suitable for low rise houses in rural areas. The real project is the first building in China to adopt the new type of soilbags seismic isolation. The filled material is the sand commonly used in the construction of the house, and the overall cost does not increase. Based on the real building, the test preliminarily verified the effectiveness of the soilbags isolation layer under the in-situ condition based on an excitation test, which provides a new beneficial reference for the seismic isolation and disaster reduction of buildings in urban and r
