纯摩擦滑移结构对双向谐和地面运动的反应Ｒ．Ｓ．Ｊａｎｇｉｄ１前言基底隔震作为一种抗震设计方法的思想，其建筑物是利用减小向结构传递水平加速度的装置来防御地震灾害的。基底隔震的主要概念，是将结构的基本振动频率减小到低于地震地面运动所包含的主要能量部分的振... Pure friction sliding structure response to bidirectional harmonic ground motion. S. Jangid1 Foreword As a kind of seismic design method, the basement isolation method uses the device that reduces the horizontal acceleration to the structure to prevent earthquake disasters. The main concept of basement isolation is to reduce the basic vibration frequency of the structure to less than the main energy contained in the seismic ground motion...
