In order to propose an equivalent fatigue vehicle suitable for the actual traffic flow, the vehicle load characteristics and fatigue vehicle load models were investigated based on WIM database in a Yangtze River highway bridge. The research results show that the bridge has the characteristics of large traffic volume, high proportion of heavy vehicles and severe overloading. All the vehicles can be divided into 6 types based on the wheelbase, and the fatigue vehicles with an equivalent vehicle weight greater than 10 t accounted for 85.9%, of which 6-axle vehicles dominated the fatigue damage. Compared with the Eurocode’s four-axle standard fatigue vehicle, the single axle weight derived from the actual traffic flow in this paper is 1.30 times that of the standard fatigue load model, which can provide guidance for fatigue design and maintenance of the same type bridges in the area. |
