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. [ABSTRACT FROM AUTHOR]

Realistic traffic load models for reassessment of Gänstor Bridge over the Danube The Gänstor Bridge over the Danube erected in 1950 is a historical bridge structure, connecting the two cities of Ulm and Neu‐Ulm. Due to increasingly occurring deficiencies and damages on the structure throughout its previous service life, extensive measures regarding structural reassessment and evaluation have been initiated. An object specific evaluation of traffic load models serves as an important element in this concept. For this purpose, realistic modelling of the actual traffic load demands is performed by means of precise object reference regarding traffic and structure. Monitoring of local traffic on the bridge to analyze local traffic characteristics has been performed. The findings serve as input for numerical simulations performed subsequently to model traffic loading on the bridge for different scenarios of traffic routing. Results from these simulations allow for an evaluation of actual traffic loading, and hence a validation of load models considered in bridge reassessment. Additional verification of results is obtained by comparison with simultaneously detected and belatedly provided monitoring data from strain gauges applied to some of the tendons of the structure.
