the paper studies the dynamic characteristics of the frame-based super-high-rise building by applying large-scale analysis software Mi-das/ Gen. Results show that:under the high-order vibration mode,the top framework will produce obvious high-order vibration. Under some spe-cial conditions,when there is no difference of self-vibration frequency of the top framework,self-vibration frequency of the lower body and ground vibration frequency,resonance reaction will occur,however,the accessory top framework will suffer from serious“whiplash effect”.%利用大型通用分析软件 Midas／ Gen，对某带构架超高层建筑的动力特性进行了研究，结果表明该类建筑在高阶振型下，顶部的构架会产生明显的高阶振动，当在某些特殊情况下，顶部构架的自振频率、下部主体的自振频率与地面振动的频率三者相差不大时，将产生共振反应，顶部附属构架会遭受严重的“鞭梢效应”。
