Under this background, the mixed posed of steel -reinforced concrete are widely used in train stations, stadiums, concert hall, theatreandthe public buildings with larger crowds. Energy dissipation technology is through the arrangement of bearings and ic energy dissipation damperonthe premise that does not affect the conformationof the mainbuilding structure,for the purpose ofeliminating isolation, increasing structural damping, dissipating the seismicenergy in the main structure. By applying the energy dissipation technology,Not only the building is kept good without damage in the earthquake, but also the equipment in the building can be maintainedconvenientlyafter the earthquakeandthe functions of the building canberestored quickly. The base of isolation technology and the damping principle of energy technologyareexpoundedbriefly and several bearings and energy dissipation damper's mecha
