This study aims to develop a risk analysis platform for a vehicle over a bridge deck during strong side wind. Two key procedures are presented for risk assessment. One is a proposition of a static model of vehicle for 16 different wind directions. This static model is used in developing so-called critical wind speed curve (CWC) and has been validated by a well-established vehicle-dynamics software, TRUCKSIM. The other is developing probabilistic model of wind speed over a bridge deck from the long-term wind data near the bridge site. The proposed methodology was applied to the Gwangan Bridge, a sea-crossing suspension bridge with the main span of 500 m in length. The parametric study demonstrated vehicle speed and payload of the vehicle were key parameters which effected on the vehicle vulnerability. Especially, it was demonstrated that a vehicle was exposed to more unfavourable condition in curved part of the bridge. |
