EVALUATION OF EXTREME TRAFFIC LOAD EFFECTS IN CABLE STAYED AND SUSPENSION BRIDGES USING WIM RECORDS

The evaluation of load effects is fundamental for assessing bridge reliability. This paper presents an approach for extrapolating traffic effects to any return period. This method is performed through optimal fittings of Rice's formula from the tail of the level crossings histograms issued from the combination of WIM records and influence surfaces. Based on statistical tests, that allows the determination of an optimal number of classes to take into account in the fittings. The study of the load effects on the stay cables of the Burgundy bridge and of the total load supported by the main span of the Tancarville bridge highlights the use of the proposed method. For the covering abstract see IRRD E102667.
