Since history, the earthquake activities are frequent in all countries, and thousands of destructive earthquakes are recorded in history, which causes serious disasters and accounts for a great proportion of the seven natural disasters. The earthquake motion situation of the whole country of nearly two thousand years or more is seen, and the earthquake motion situation has the basic characteristics of high frequency, high strength and wide distribution and has profound influence on human activities. The building engineering is the most main carrier of human activities, and the bridge engineering is the throat of road traffic. In view of the accidental action of earthquake, in order to effectively protect the life and property safety of people, the building and the bridge structure usually adopt relatively economic, simple and advanced seismic isolation technology. Seismic isolation and reduction supports are the most common and efficient engineering measures, and an effective means for protecting a main structure from seismic damage is to consume and buffer ground vibration through the supports.

The traditional rubber support has the advantages of small vertical bearing capacity, small horizontal shearing rigidity, poor rotation capacity, easy damage due to stress and no self-resetting function due to the mechanical property and durability of the material; the traditional spherical steel support has large material consumption, does not have a shearing deformation function, and needs to additionally add damping to realize deformation energy consumption. Therefore, the support with an innovative structure is urgently needed, the advantages of the traditional rubber support and the advantages of the traditional steel support are combined, and the characteristics of high bearing capacity, large shearing deformation, strong energy consumption capacity and strong self-resetting function are achieved.
