Abstract

The invention discloses a main arch boom wind-resistant shock absorbing structure. The main arch boom wind-resistant shock absorbing structure comprises a main arch, a floor beam and booms. The floorbeam is laterally disposed at the lower portion of the main arch, the two ends of the floor beam are respectively mounted on the main arch, a plurality of vertically disposed booms are evenly distributed between the main arch and the floor beam, and the upper ends of the booms are fixedly connected with the main arch, and the lower ends of the booms are fixedly connected with the floor beam. The floor beam is provided with a floor panel. The main arch boom wind-resistant shock absorbing structure further comprises a wind-resistant damper device, wherein the wind-resistant damper device comprises an anti-wind cable, rope bayonets, and a reaction force frame. The anti-winding cable is disposed laterally, and the anti-winding cable is fixedly connected to the booms by the rope bayonets, the two ends of the anti-winding cable are respectively connected to the main arch through the reaction force frame, and a limiting device is arranged between the floor beam and the main arch. The structure can solve the technical problem that the arch bridge booms have low wind resistance.

Description

technical field [0001] The invention relates to the technical field of shock absorbing devices for arch bridges, in particular to a wind-resistant and shock-absorbing structure of a main arch suspender. Background technique [0002] Concrete-filled steel tube arch bridges have the advantages of reasonable stress, economy, good durability, and convenient construction. They have developed rapidly in my country and are widely used. So far, more than 400 bridges have been built. In recent years, the span of concrete-filled steel tube arch bridges has become larger and larger, and the length of the main arch suspension cables has also become longer and longer. At present, the maximum suspension cable length of arch bridges has exceeded 100 meters. The dynamic response of loads such as driving and earthquakes is becoming more and more difficult to coordinate. Therefore, in order to improve the overall performance of the main arch suspension structure, increase the natural frequenc...
