【摘要】 对不同地震烈度作用下的摩擦摆基础隔震结构进行了地震反应分析,分析了支座摩擦系数对支座位移、楼层加速度和楼层剪力的影响。结果表明随着摩擦摆支座摩擦系数的增大,支座位移逐渐减小,而结构的加速度和楼层剪力逐渐增大;随着地震作用强度的提高,摩擦系数对支座位移的影响逐渐增大,而摩擦系数对结构加速度和楼层剪力的影响逐渐减小。更多还原

【Abstract】 The seismic response of base-isolated structure with friction pendulum system to different earthquake intensities was carried out.The influence of the friction coefficient of bearing on its displacement,the acceleration of the structure and the inter-story shear force was analyzed.The results show that as the friction coefficient increasing,the displacement of the bearing will decrease,while the acceleration of the structure and the inter-story shear force will increase.As the intensity of the earthquake action increasing,the influence of the friction coefficient on the displacement of the bearing becomes larger,but its influence on the acceleration of the structure and the inter-story shear force becomes less.更多还原
