In this paper,a novel isolation device with high damping ratio was developed and introduced.Base on a designed Y style mega-sub steel structure model closed to a real engineering,the shaking table tests of the traditional mega-sub anti-seismic system and the new mega-sub control system set by the novel isolation devices were carried out separately.The results show that the response of the mage-sub control system under earthquake excitation is much less than that of the traditional mage-sub anti-seismic system and can be controlled well.The seismic reduction mechanism of this control system observed from the experiment is identical with the result from theoretical analysis.The conclusion of the research can be used as a reference for engineering design and application.
