Traffic Parameter Sensitivity in the Development of Site-specific Load Models

Extensive numeric parameter studies estimating extreme load effects on a set of different structures and traffic constellations are performed, to gain a better understanding of the underlying correlations, and hence support the development of strategies to identify those sections of the highway network promising the highest potential for the application of site-specific load models in bridge reassessment. This paper presents a general approach for developing site-specific load models based on recorded traffic data, and discusses first findings and results gained from the above described parameter study.
