Implication

Wind tunnel tests reveal that increasing barrier height reduces overturning moments in a steel box-truss girder, indicating effects on vortex-induced vibrations and vehicle aerodynamics.

Key Points

Notable vortex-induced vibrations occur with wind barriers, affecting aerodynamic performance.
Vortex-induced vibration resistance is good without barriers; however, responses increase with their addition.
Wind tunnel tests assess barrier height and porosity effects on aerodynamic forces and VIV.
CFD simulations show that design adjustments can suppress periodic vortex shedding at the trailing edge.
