Based on the Xiangjiaba Hydro Project, dynamic characteristics of large high-rise structure under El_Centro seismic wave were investigated in this paper. 8-node hexahedral isoparametric elements are used to the solid element in the 3-D finite element model. In order to increase the efficiency of the calculation, the Newmark-  method is implemented. By means of seismic waves, the displacement responses of the Xiangjiaba Hydro Project are analyzed in detail. The results, which are obtained for displacement responses of tower columns of ship lift, show that calculated dynamic results of the tower column can meet the design requirements.
