Abstract: A platform to evaluate the vulnerability of running vehicles over the bridgedeck is proposed for the assessment of strong wind hazards on driving mobility..The platform utilizes wind tunnel tests, dynamic s imulations of nmning· vehicles, wind environmental analysis based on long-term wind data. Threeaccidents types of roll over, side slip, and rotation are considered. The criticalwind speed curves are developed according to the vehicle speeds and roadconditions by combined use of the quasi-static approach and dynamic approach,in which all the wind directions and lane positions are taken into consideration,A prototype application is demonstrated for the Gwanan Suspension Bridge composed of double-deck girders. The critical wind speeds are evaluated foreach lanc in each wind direction and the traffic control wind speeds and controlscenarios arc suggesibd. The overall vulnerability indices are also evaluated based on the accumulate data.
