Abstract

The invention provides an assembled bridge double-column pier with a triple energy consumption system, which includes a bearing platform, a steel pipe concrete pier is installed on the left and right sides of the upper part of the bearing platform, and extrusion damping is arranged between the steel pipe concrete bridge pier and the bearing platform Concrete-filled steel tube cover beams are installed between the concrete-filled steel tube piers on both sides. The left and right ends of the concrete-filled steel tube cover beams are respectively equipped with steel shear ear plates. The other end is fixed to the concrete-filled steel pipe pier by bolts; a cymbal-shaped disc reed is arranged above the steel shear ear plate, and the cymbal-shaped disc reed is located between the concrete-filled steel pipe pier and the concrete-filled steel pipe cover beam; An anti-buckling plate assembly is installed under the ear-shearing plate. One end of the anti-buckling plate assembly is fixed to the concrete-filled steel tube pier through bolts, and the other end is fixed to the concrete-filled steel tube cap beam through bolts. By setting a triple energy dissipation system, the design is facilitated. And construction, to avoid damage and damage occurred under strong earthquakes.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to an assembled bridge double-column pier with a triple energy consumption system. Background technique [0002] Double-column piers are the main anti-gravity and lateral force components of bridge engineering. The current double-column piers are mostly reinforced concrete structures. The difficulties in their design and construction include: (1) The cover beam is rigidly connected to the bridge pier. The mechanism is complex, and the design and analysis are extremely difficult. (2) In order to meet the design requirements of reinforced concrete cover beams, a large number of steel bars are arranged in the cover beams, resulting in dense reinforcement in the cover beams and difficult construction. (3) Under strong earthquakes, the double-column pier was seriously damaged, and it was not easy to repair after the earthquake, resulting in the interruption of the traffic lifeline proje...
