摘要
根据非比例阻尼隔震结构的动力特性,提出了非比例阻尼隔震结构平扭耦联振动的运动方程.分析了地震作用下,非比例阻尼隔震结构平扭耦联振动反应,并讨论了隔震层和上部结构的偏心及质量偏心对结构动力响应的影响.
According to the dynamic features of isolation structures, the motion equation of torsional vibration in non-proportionally damped isolation structures is presented. The torsional vibration in these structures is analyzed, and the influences of the eccentricity of the system and super-structure on dynamic response are also discussed.
