Abstract

The invention discloses an installation structure for improving the energy dissipation capacity of a bridge pier, comprising a bridge pier, a cover beam, a beam body, a friction pendulum support and a laminated rubber support, the cover beam is fixed to the top of the bridge pier, and the cover beam is U-shaped , the two sides of the cover beam are respectively provided with side walls extending vertically upwards, one end of the friction pendulum support is fixed to the top surface of the cover beam, the other end is fixed to the web of the T-beam body, and one end of the laminated rubber support It is fixed to the web side of the T-beam body and the other end is fixed to the side wall of the cap beam. Through the function-separated external replaceable energy-dissipating device formed by the parallel connection of the friction pendulum bearing and the laminated rubber bearing, the two shock-absorbing and isolating bearings are not coupled, and the force transmission path of the combined device is clear, and the functions of each component Single, easy to refine design and control, and can be widely used in bridge piers in earthquake zones. Combining the two types of shock-absorbing and isolating bearings can give full play to the advantages of large vertical bearing capacity, good self-resetting ability of the friction pendulum bearing, and strong hysteretic energy dissipation performance of the laminated rubber bearing.

Description

technical field [0001] The invention relates to the technical field of shock absorption and energy consumption of bridge piers, in particular to an installation structure for improving the energy dissipation capacity of bridge piers. Background technique [0002] With the development of bridge technology, the proportion of bridges in highways and railways is increasing, and the impact of earthquake force on bridge safety has attracted more and more attention of bridge workers. Among them, the energy dissipation and shock absorption performance of bridge piers has become an important performance index for its popularization and application in bridge engineering in medium and high intensity areas. In particular, prefabricated segmental piers have large displacement requirements and poor energy dissipation capacity under earthquake action, which has become a problem that must be solved for their popularization and application in bridge engineering in medium and high intensity a...
