Du Yong-feng1,2,Lin Zhi-dan2(1.West Engineering Research Center for Disaster Mitigation in Civil Engineering,Ministry of Education,Lanzhou 730050,China;2.Institute of Earthquake Protection and Disaster Mitigation,Lanzhou Univ.of Tech.,Lanzhou 730050,China)  
The structure that the rubber isolation pad is connected with the cantilever column is often used at home and abroad.In this paper,a vibration control strategy for serially connected isolated structures is proposed.That is control devices are installed at the isolation level.The equation motion of the vibration control system to the serially connected isolated structures subjected to two-directional horizontal earthquake is established,and the effect which the flexibility of the bottom in the serially connected isolated structures to the stiffness is considered.Sequential Optimal Control algorithm is used to control the example.The results show that the isolated control strategy is very effective in reducing structure seismic response under the two-directional horizontal earthquake,and the movent of isolation layer is reduced at least 63.1%.So the wholly stability of structure can be improved effectively.
