Abstract In order to investigate the characteristics of the vortex-induced high-mode vibration (VIV) of a flat box girder, the flow field around the flat box girder was solved based on the Reynolds averaged Navier-Stokes (RANS) equation and the SST k-ω turbulence model in combination of the dynamic mesh technology.The dynamic response of the structure was solved by the Newmark-β integration method which was embedded in Fluent user defined functions (UDFs).The estimation of high-mode VIV responses of the stiffened girder of the Great Belt East Bridge main crossing was carried out under the Reynolds number from 3.18×104 to 6.10×104.The study presents the time histories of acceleration responses and the RMS value of vibration amplitudes at various reduced wind speeds, and the lock-in region of VIV agrees well with that in literatures.Also, the effects of damping ratio and wind angle of attack on the displacement and acceleration responses of the stiffened girder were studied.The results show that as the damping ratio increases, the response of VIV becomes smaller and even finally disappears, while remarkable VIV can be recognized only when the wind angle of attack is larger than 2°.
