摘要
对单轴偏心的单层基础隔震框架结构地震反应进行了分析,并建立其运动方程.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:基础隔震对于存在扭转变形的结构来说,随着结构偏心率的增大。
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 under different eccentricity with or without base
isolation. Eccentricity ratio increases with the increase of the response ratio R for the response in
the eccentricity. This indicates that the effectiveness of base isolation for a torsion system
decreases with the increase in the system eccentricity.
