Taking a practical engineering as an example, the state space method was used to calculate the maximum displacement, the maximum shear response, and the hysteretic time-history response of parallel composite isolated structure subjected to different characteristics of earthquake ground motions. The results show that parallel composite isolated structure can give full play to advantages of different types of isolated bearings and effectively reduce the seismic responses of the superstructure; different characteristics of earthquake ground motions have important effects on seismic responses of parallel composite isolated structure. Those results can provide some guidance for the design of parallel composite isolated structure.
