APPLICATION OF WEIGH-IN-MOTION DATA TO FATIGUE OF ROAD BRIDGES

Fatigue assessment of steel and composite bridges is one of the most demanding application of Weigh-In-Motion (WIM) in bridge engineering. Traffic data about axle and vehicle loads, spacing and volume are required to calculate fatigue damage and bridge lifetimes, to calibrate the conventional fatigue load models in the codes (and Eurocodes) and to check existing bridge reliability. An overview of the methods commonly used for bridge fatigue assessment is presented. Some information is given about the traffic data required and the fatigue load models of the Eurocode 1 Part 3. Finally some examples are given to show the sensitivity of the reliability of bridge details to traffic characteristics. For the covering abstract see IRRD E102667.
