Experimental Study on Wind Environment of Vehicles Running on a Cable-Stayed Twin-Deck Bridge
Publication: Resilience and Sustainable Transportation Systems
ABSTRACT
Strong wind is a grave threat to the vehicles running on bridges. The cross wind environment of twin-deck bridges is much more complicated than the single deck bridges. In this study, by taking the 12.45 km Quanzhou Bay Bridge in Fujian Province as an example, a simplified cross wind environment assessment method for vehicles running on bridges is proposed; then the cross wind environment of the twin-deck bridge is investigated using the aforementioned assessment method collaborated with wind tunnel tests. The results show that the equivalent wind speeds on the bridge deck do not satisfy the requirement of the allowable equivalent wind speed factor. Thus, a cross wind mitigation measure of wind fence is proposed. Finally, the effects of the wind fence and the aeroelastic stability of the bridge after installing the wind fence are examined.
