| description | This paper investigates aerodynamic countermeasures for a cable-stayed bridge with 2-edge I-shaped girder section. Wind tunnel tests were conducted in order to confirm the performance of the new countermeasure by using the essential attachments. Some structural countermeasures by increasing bridge rigidity were also investigated. In this study, adding a horizontal member at the top of the tower is most effective for increasing the flutter onset velocity. In conclusion, these aerodynamic countermeasures can be economical countermeasures. |
