摘　　要：超高层框架-钢筋混凝土核心简结构采用粘滞阻尼器进行消能减震,在地震大震、中震、小震作用下,使用弹性(弹塑性)动力时程分析法,对比减震结构与非减震结构的位移、剪力以及附加阻尼比,来观察超高层建筑的减震效果并判断是否达到相关规范的要求。Viscous dampers were used to dissipate energy and reduce vibration in super high-rise frame reinforced concrete core simple structure.Under the action of large earthquake,medium earthquake and small earthquake,the elastic(elastic-plastic)dynamic time history analysis method was used to compare the displacement,shear force and additional damping ratio between the damping structure and the non damping structure,so as to observe the damping effect of the super high-rise building and judge whether it can meet the requirements of relevant specifications.

关 键 词：超高层建筑 附加阻尼比 消能减震 弹性动力时程分析
