【摘要】 对摩擦摆基础隔震结构进行了地震反应分析,研究了支座滑道半径对支座位移、楼层加速度和楼层剪力的影响,表明当支座的摩擦系数较小时,随着支座滑道半径的增大,隔震结构的自振周期增大,摩擦摆支座位移逐渐增大,结构的加速度反应和楼层剪力减小;当支座的摩擦系数较大时,改变支座的滑道半径,调整基础隔震结构周期对支座位移、结构加速度反应和楼层剪力的影响较小。更多还原

【Abstract】 The seismic responses of the base-isolated structure with friction pendulum system were analyzed.The influence of the radius of the spherical surface on the displacement of the bearing,the acceleration of the structure and the inter-story shear force were calculated.If the friction coefficient of the bearing is small,as the radius increases,the periods of the structure and the displacement of the bearing will increase,the acceleration of the structure and the shear force will decrease.If the friction coefficient is large,the influence of the radius of the spherical surface on the seismic responses of the structure becomes little.更多还原
