| Abstract: | The important property of layered compound materials is band gap, which forbidden the elastic waves to travel in. By changing the structure of materials and the properties of materials, the resonance frequency of the building could fall with in the scope of the band gap frequency, and the vibration effect will be restrained. The seismic capacity of buildings in earthquake could be effectively improved. This paper introduces the application of the layered phononic-crystal materials in buildings＇ seismic disaster. |
