An energy-consuming swinging bridge pier

Abstract

The invention relates to the technical field of bridges, and specifically discloses an energy-consuming swinging bridge pier. It includes a bridge deck, a connecting seat, a first base, a bridge pier and a second base, one end of the bridge pier is fixedly connected to the first base, the other end of the bridge pier is located in the second base, and the connecting seat is symmetrical Placed on both sides of the upper surface of the first base, the bridge deck is located on the connecting seat, the interior of the second base is provided with an arc-shaped groove, and the arc-shaped groove is provided with an arc-shaped block, and the arc The shaped block can be deflected in the arc-shaped groove, one end of the bridge pier is fixedly connected to the middle of the arc-shaped block, at least two groups of rocking mechanisms are arranged above the base, and the adjacent two groups of rocking mechanisms are clamped. connected, the bridge pier penetrates through the middle of the rocking mechanism, and the bridge pier and the rocking mechanism are slidably connected. The technical solution is used to improve the seismic effect of the bridge and reduce the damage caused by the earthquake to the bridge.

Description

technical field [0001] The invention relates to the technical field of bridges, and specifically discloses an energy-consuming swinging bridge pier. Background technique [0002] my country is located between the Pacific Rim Seismic Belt and the Eurasian Seismic Belt. Most of the country is an earthquake zone, especially the western part of our country, which is mostly a strong earthquake zone and has frequent seismic activities. Bridges are the pivotal engineering of the lifeline of transportation, and their construction costs are high. Once damaged by an earthquake, it will lead to huge economic losses, and it is extremely difficult to repair after the earthquake. The number of casualties directly on the bridge is not large, but the economic losses and casualties caused by the damage and interruption of traffic lifelines are immeasurable, resulting in the inability of rescuers to arrive in time, and many people have not been rescued in time, aggravating the earthquake disa...

AI Technical Summary

Problems solved by technology

The bridge is a pivotal project of the traffic lifeline, and its construction cost is high. Once it is damaged by an earthquake, it will cause huge economic losses, and it is extremely difficult to repair after the earthquake

The number of casualties directly on the bridge is not many, but the economic losses and casualties caused by the damage and interruption of the traffic lifeline are immeasurable, resulting in the failure of rescue personnel to arrive in time, and many people have aggravated the earthquake disaster because they did not receive timely rescue.

At the same time, it is difficult to repair the damaged large bridges, which seriously affects the production and life in the disaster area and the post-disaster reconstruction work

The current seismic design of bridges is mainly based on the ductile seismic design of the hysteretic performance of reinforced concrete piers, but it is difficult to repair the damage and destruction of the plastic hinge area of ​​bridge piers
