Bridge structure with transverse shock absorption and isolation supporting system

Abstract

The invention relates to a bridge structure with a transverse shock absorption and isolation supporting system, and belongs to the technical field of bridge shock absorption, the bridge structure comprises a bridge tower and a main beam, the bridge tower comprises two tower columns and a bridge tower cross beam located between the two tower columns, and the main beam is located between the two tower columns and located at the top of the bridge tower cross beam; a transverse support is located between the main beam and the tower column, one end of the transverse support is fixedly connected with the main beam, and the other end of the transverse support can make contact with the tower column and longitudinally slide; and a transverse damper is located between the main beam and the tower column, one end of the transverse damper is connected with the main beam, the other end of the transverse damper does not make contact with the tower column, and after the transverse support is cut off, the other end of the transverse damper makes contact with the tower column all the time and is in sliding connection with the tower column. According to the bridge structure, when the transverse support reaches the rated shearing force and stops working, the transverse damper starts to intervene and exert the energy dissipation and shock absorption effect, and the purposes of shock absorption and energy dissipation are achieved. Bolt holes do not need to be formed in webs of girders, additional connecting plates do not need to be welded to top plates or bottom plates of the girders, and the durability of the girders is higher.

Description

technical field [0001] The present application relates to the technical field of bridge shock absorption, in particular to a bridge structure with a lateral shock absorption and isolation support system. Background technique [0002] With the development of bridge technology, the spanning capacity and adaptability of bridges are required to be further improved, and there are more and more long-span cable bridges in high-intensity areas. A transverse support is usually required between the pylon and the main girder of a long-span flexible cable-bearing bridge. The transverse support can effectively limit the transverse displacement of the main girder caused by wind load or earthquake load, and transmit the transverse horizontal force borne by the main girder. to the bridge tower. [0003] However, for long-span flexible cable-bearing bridges in high-intensity areas, seismic loads often control the design of bridge structures. In order to reduce shock and energy consumption, ...
