Energy dissipation pier structure and construction method and application thereof

Abstract

The invention discloses an energy dissipation and seismic mitigation pier structure and a construction method and application thereof.The energy dissipation and seismic mitigation pier structure comprises hollow piers, cross beams, disc spring self-resetting energy dissipaters, rubber seismic isolation cushion layers and foam concrete columns, the foam concrete columns are arranged in the middlesof the hollow piers, and the cross beams are arranged between the hollow piers and the foam concrete columns at intervals; wherein the cross beam is connected with the foam concrete column through thedisc spring self-resetting energy dissipater, the disc spring self-resetting energy dissipater is connected with the cross beam through bolts, the disc spring self-resetting energy dissipater is connected with the foam concrete column through bolts, and a rubber shock insulation cushion layer is arranged between the disc spring self-resetting energy dissipater and the foam concrete column. Energydissipation, seismic mitigation and self-resetting capacity of the bridge pier structure in all directions under the action of seismic loads is achieved, the seismic capacity of the bridge structureis improved, and good economic benefits and engineering application prospects are achieved; the foam concrete columns and the cross beams are poured while the hollow pier is poured, the foam concretecolumns are reinforced, the structure bearing capacity is improved, the structure is simple, and construction is convenient.

Description

technical field [0001] The invention relates to a bridge pier structure based on the energy-absorbing and shock-absorbing functions of foam concrete, in particular to a structure suitable for the seismic response control of bridge piers in bridge engineering, and belongs to the technical fields of bridge earthquake resistance and bridge shock absorption and isolation. Background technique [0002] my country is a country with serious earthquake disasters, which has the characteristics of high earthquake frequency, high intensity, shallow focus, and wide distribution. Therefore, how to improve the earthquake resistance of bridges and reduce the damage to bridge structures caused by earthquakes will bring great challenges to the earthquake resistance design of bridges. Here comes the great challenge. [0003] In view of the serious destructive effects of earthquakes on bridges, measures such as using shock-absorbing and isolating bearings, setting up base-isolation layers, and ...

AI Technical Summary

Problems solved by technology

Although the patents can interact with each other for shock absorption and energy consumption, the anti-seismic effect is good, and the service life is long, but the self-resetting ability of the bridge pier is weak, and the safety of the bridge needs to be further improved
