Determination of object-specific traffic-load-models for existing road bridges based on traffic data

For an assessment of the necessity, the efficiency and the prioritization of repair and upgrading measures for bridges, object-specific knowledge of structural stresses and structural conditions is indispensable. From the identification of traffic occupancy (quantity and quality) and the analysis of the structural reactions, statements on the current load-bearing capacity of an existing bridge will derived. A necessary data basis is the traffic data of the real traffic determined for the specific bridge.
