Flange-connecting concrete-filled double-wall steel pipe prefabricated assembly piers with additional dampers
The invention discloses flange-connecting concrete-filled double-wall steel pipe prefabricated assembly piers with additional dampers. The piers comprise a bearing table, prefabricated assembly pier bodies and a cover beam. The piers are characterized in that the bearing table, the prefabricated assembly pier bodies and the cover beam are connected through flanges to form a whole, the prefabricated assembly pier bodies are concrete-filled double-wall steel pipe prefabricated assembly pier bodies, each prefabricated assembly pier body comprises an outer steel pipe, an inner steel pipe and filled concrete, and the four viscous dampers are arranged between the top face of the bearing table and the end faces of the prefabricated assembly pier bodies as well as between the bottom face of the cover beam and the end faces of the prefabricated assembly pier bodies. The piers have the advantages that the construction quality is improved, the construction speed is increased, the site operation amount is reduced, and the impact on the environment is reduced; the viscous dampers provide additional energy-consuming abilities for the piers, and therefore the displacement requirement of the piers under horizontal load effects of earthquakes and the like can be controlled and reduced.
