目前，由于长周期地震动的缺乏，国内外对于长周期地震动特性及在长周期地震动作用下的超高层结构地震响应的研究尚不成熟。该文选取长周期地震动Tom波、地表反应波LS-R波、普通地震动El Centro波作为输入，对在不同类型地震波作用下的超高层结构进行了模型振动台试验，并对试验结果进行了分析。通过对三条不同类型地震波作用下超高层结构的动力响应分析，以时频分析的角度分析了超高层结构地震反应与输入地震动特性之间的关系及超高层结构在长周期地震动作用下与普通地震动作用下的地震反应差异等。

For a lack of long-periodic ground motion, studies on its features and the seismic response of super high-rise structure under long-periodic ground motion are immature. The long-period ground motion Tom wave, the ground response motion LS-R wave and the normal ground motion El Cen-tro wave are selected as three input waves, the shaking table test is done to the super high-rise structure under different types of ground motions and the results are analyzed. By analyzing the motion response of super high-rise structure under different types of seismic waves, the relation between seismic re-sponse and ground motion characteristics and the differences of seismic response under long-periodic ground motion and normal ground motion are also analyzed from the aspect of time requency.
