英文摘要：

The vibration control effectiveness of the TMD-base isolation hybrid control system under stationary stochastic seismic excitation is studied. The motion equation of the hybrid control system is established, the stochastic response of the hybrid control system is solved by using the state-space method, and the power spectrum density and root-mean-square of the hybrid control system seismic response are Obtained. The computation expression used in solving the TMD optimum parameters un- der the superstructural displacement optimization condition is given, and the vibration control effec- tiveness of the hybrid control system is analyzed and compared with base isolation structure. The a- nalysis results indicate that the hybrid control system can reduce the displacement of isolation layer and control the superstructural seismic response more effectively, and the hybrid control system still behaves well when located on different site soil.
