层式滤波隔震垫
|
摘要
根据震相图展示的地震波运动规律,利用滚动摩擦阻力只相当滑动摩擦阻力1/40~1/60的力学效应,将轴承钢球呈层状重叠组合成隔震垫,可获得重复滤波效果,能高效降低地震对房屋建筑的作用力,达到提高地震安全度,降低建筑成本、节约建筑资源的目的。
A layered earthquake partition mat composed of some superposed steel balls was presented,based on the principle of the movement of earthquake waves shown by the curves of seismic phases,and by utilizing the dynamic effect of rolling friction resistance equaling to 1/40～1/60.With such a mat,a multi-step filtering could be obtained and the force exerted to structures by earthquake could be largely reduced,leading to raising the building safety factor,lowering the building cost,and economizing the structure resources.
