AI Technical Summary
Technical Problem
The slotting between the main beams of a split steel box girder can easily lead to vortex-induced vibration, and a single aerodynamic measure is not effective in suppressing vibration.
Method used
Two adjacent steel box girders are connected by a transverse connecting beam. Wind nozzles are installed on the outside of the two steel box girders, and vortex-blocking plates and wind-resistant stabilizing components are installed on the inside. The combination of two aerodynamic measures is used to suppress vortex-induced vibration.
Benefits of technology
It effectively suppresses bridge flutter and vortex-induced vibration, improves the bridge's wind resistance, and ensures structural stability.

Abstract
This utility model relates to the field of bridge engineering technology, specifically to a split-type steel box girder vortex-induced vibration suppression structure. Two adjacent steel box girders are arranged in parallel and connected by multiple transverse connecting beams spaced longitudinally. A vent is provided on the side of each steel box girder away from the other. On the side of each steel box girder closer to the other, a vortex-blocking plate and a wind-resistant stabilizing component are provided between two adjacent transverse connecting beams. The vortex-blocking plate is connected to the top plate of the steel box girder, and the wind-resistant stabilizing component is connected to the transverse connecting beams at both ends. This utility model provides vents on the outer sides of both steel box girders and vortex-blocking plates and wind-resistant stabilizing components on the inner sides of both steel box girders. The combination of these two aerodynamic measures effectively suppresses bridge flutter and vortex-induced vibration, thereby improving the bridge's wind resistance.
