摩擦摆隔震结构的地震响应分析

基于摩擦摆（FPS）及其隔震剪切型结构的振动微分方程，进一步研究了该系统的振动形态。通过改变摩擦摆的摩擦系数和滑道半径，分析二者对结构隔震效果的影响。结果说明：摩擦系数对结构层间位移、基底剪力以及基底滑移量均有较大的影响；滑道半径对基底滑移量有较大影响，但对层间位移和基底剪力影响不大。

Analysis of seismic responses for FPS-based structures

Based on the vibration equations of friction pendulum systems(FPS)and FPS-based shear-typed buildings,the vibration performances of the systems are studied in more details.By the different coefficients of friction,slideway radius, the author has analyzed how the change of the friction coefficient and the slideway radius of the FPS system influenced isolating affection.The results show that friction coefficient is very effective on the interstory displacement and the base shear force and the sliding displacement of FPS,the slideway radius has more effect on the sliding displacement of FPS than the interstory displacement and the base shear force.
