Stay cable vibration reduction system

Abstract

The invention belongs to the technical field of stay cable vibration reduction, and particularly relates to a stay cable vibration reduction system. The system comprises a plurality of bridge piers, bridge columns, a bridge floor and a plurality of stay cables, the bridge columns are fixedly connected with the bridge piers, the bridge columns are fixedly connected with the bridge floor through thestay cables, first connecting sections are fixedly connected to each pair of bridge piers, one ends of the first connecting sections penetrate through the bridge floor, the first connecting sectionsare fixedly connected with buffer sections, the buffer sections and the stay cables are arranged in an interspersed mode, one end of each buffer section is fixedly connected with a second connecting section, and every two second connecting sections are fixedly connected through the same fixing piece. The system has the advantages that the stay cables can be effectively buffered and damped, when the stay cables are influenced by weather or address and resonance factors, the shaking amplitude of the stay cables is reduced, the effect of providing good stability is achieved, meanwhile, a traditional construction process and sequence are not damaged, excessive abrasion of the stay cables is further prevented, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of cable damping, and in particular relates to a cable-stayed damping system. Background technique [0002] Cable-stayed bridges have steel cables tied to the bridge columns. The steel cables support the weight of the bridge deck and transfer the weight to the bridge columns, causing the bridge columns to withstand enormous pressure. Cable-stayed bridges are an important structure of modern long-span bridges Especially when erecting super-large bridges with long spans across canyons, bays, large rivers, rivers and other places where piers are not easy to build, the bridge types of suspension bridges and cable-stayed bridges are often selected. [0003] The core of the cable-stayed bridge lies in multiple stay cables, which provide the supporting tension for the docking of the two sides. However, this type of bridge also has disadvantages. The main point is that it is greatly affected by the steel cables. It...

[0003] The core of the cable-stayed bridge lies in multiple stay cables, which provide the supporting tension for the docking of the two sides. However, this type of bridge also has disadvantages. The main point is that it is greatly affected by the steel cables. It can provide rigid support like a permanently poured concrete bridge body. Although it will not pose a threat to the bridge body itself, it will easily cause the bridge deck to be unstable, and long-term use will also easily lead to the disadvantages of reducing the service life of the swaying cables.
