Abstract

The application relates to a split-type arc bottom steel box girder, which relates to the field of bridge engineering. The steel box girder includes n boxes and n-1 cross beams between boxes, n≥2, and any two adjacent boxes pass through one The cross beams between the boxes are connected, and the connection section between the bottom plate of the box and the beam between the boxes is arc-shaped, and the reinforced structure is arranged at the connection between the bottom plate of the box and the bottom plate of the beam of the beam between the boxes, and the reinforced structure The components are arranged on the inner side of the bottom plate of the box body. The present application solves the technical problem of poor vortex vibration performance of the split steel box girder.

Description

technical field [0001] The application relates to the field of bridge engineering, in particular to a split-type arc bottom steel box girder. Background technique [0002] At present, in long-span bridge engineering, the common main girder section is an integral steel box girder, and the main girder is composed of streamlined boxes. However, when the ambient wind speed in the bridge site area is very high, the flutter stability of the long-span bridge using the integral steel box girder as the main girder is poor, and the wind resistance performance cannot meet the requirements. [0003] In related technologies, in order to solve the above problems, many bridges use split steel box girders (see Figure 1); specifically, split steel box girders are composed of n (n≥2) boxes and n-1 crossbeams between boxes , a plurality of boxes are arranged at equal intervals along the transverse bridge direction on the beams between the boxes. [0004] Although the split steel box girder i...
