摘要：

Twin-box girders have been widely used in long-span cable-supported bridges for their excellent performance against flutter. Using aerodynamic counter-measures to weaken the large vortices in the slotting is the most effective way to control the vibration for twin-box decks that suffer vortex-induced vibration (VIV). This paper compares the effects of central horizontal plates with different openings on the VIV of a twin-box girder through wind tunnel tests on a large-scale sectional model. The results show that twin-side plates have the best VIV control effects with a similar opening rate. Plates with other types of openings can reach the same level of control effects as the twin-side plates with about 26% less opening rate and among such plates, unevenly distributed openings have better VIV control effects. © 2023 Chinese Vibration Engineering Society.
