摘要
建立了单轴偏心的单层基础隔震框架结构的运动方程,计算了在不同偏心率情况下结 构模型的地震反应.结果表明。对于存在扭转变形的结构来说.随着结构偏心率的增大,基础隔震的效率降低。
An analysis of a one-story frame model of base-isolated building is presented. The equations of motion of the system are given. The response of the system is obtained for different eccentricity with and without base isolation. It is shown that the response ratio increases significantly with increase of eccentricity of the structure This indicates that the effectiveness of base isolation for a torsion system decreases with the increase of eccentricity of the system.
