Experimental study on characteristics of vortex-induced vibration of a twin-box girder and damping effects

Journal of Fluids and Structures, 2021
Abstract To investigate the characteristics of vortex-induced vibration (VIV) of the twin-box girder, we carried out the VIV wind tunnel tests. The VIV of the twin-box girder occurs in the range of 4.680 ≤ U r ≤ 6.113, with the maximum dimensionless VIV displacement RMS(y)/D=0.03308 at reduced velocity at U r = 5 .

A numerical investigation of Reynolds number sensitivity of flow characteristics around a twin-box girder

Journal of Wind Engineering and Industrial Aerodynamics, 2018
Abstract A numerical investigation of Reynolds number sensitivity on flow past a twin-box girder was performed using large eddy simulation (LES) with Reynolds numbers of 1e2 ≤ Re ≤ 1e7. The simulation results reveal that the flow characteristics around the twin-box girder show different Reynolds number sensitivity according to the flow region and the

Benefits and Challenges of the Twin-box Bridge Girder

IABSE Congress Reports, 2022
<p>The aerodynamics of the twin-box bridge is considered to highlight the reasons for making this type of bridge deck superior to the conventional trapezoidal mono-box for suspension bridges having span lengths longer than 1800 m. The paper proposes a simple theoretical model yielding physical insight into the flutter stability and presents a ...
