周期性层状材料在建筑抗震方面的应用探索
|
摘要
利用弹性波在周期层状材料中的禁带带隙,通过改变材料组成尺寸,使得建筑物的共振频率落在禁带范围内,达到抑制振动的效果,可以有效提高建筑物在地震中的抗震能力。介绍了层状声子晶体材料在建筑物抗震中的应用。
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.
