Abstract

The invention provides a fabricated bridge double-column pier with a triple energy dissipation system. The double-column pier comprises a bearing platform, the left side and the right side of the upper portion of the bearing platform are each provided with a concrete-filled steel tube pier, and extrusion dampers are arranged between the concrete-filled steel tube piers and the bearing platform; aconcrete-filled steel tube bent cap is installed between the concrete-filled steel tube piers on the two sides, steel shear-resistant lug plates are arranged at the left end and the right end of the concrete-filled steel tube bent cap respectively, one end of each steel shear-resistant lug plate is welded to the middle of the concrete-filled steel tube bent cap, and the other end of each steel shear-resistant lug plate is fixedly connected with the corresponding concrete-filled steel tube pier through bolts; cymbal-shaped disc reeds are arranged above the steel shear-resistant lug plates, andare positioned between the concrete-filled steel tube piers and the concrete-filled steel tube bent cap; a buckling-restrained plate assembly is arranged below each steel shear-resisting lug plate, one end of the buckling-restrained plate assembly is fixedly connected with the corresponding concrete-filled steel tube pier through bolts, and the other end of the buckling-restrained plate assembly is fixedly connected with the concrete-filled steel tube bent cap through bolts. By arranging a triple energy consumption system, design and construction are facilitated, and damage caused by strong earthquakes is avoided.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to a prefabricated bridge double-column pier with triple energy dissipation systems. Background technique [0002] Double-column piers are the main anti-gravity and lateral force components of bridge engineering. Most of the current double-column piers are reinforced concrete structures. The difficulties in their design and construction include: (1) The rigid connection between the cover beam and the bridge pier, due to the mechanical 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, which makes the steel bars in the cover beams dense and difficult to construct. (3) Under the strong earthquake, the double-column pier suffered serious earthquake damage, and it was not easy to repair after the earthquake, resulting...
