Temperature in the Box Girder of the Normandy Bridge

This paper deals with the analysis of the temperature records obtained for the Normandy Bridge [1], in particular for the orthotropic steel box girder. After a short description of the measuring equipment and of the goals of the analysis, daily cycles are briefly described. Then the distribution of extreme temperatures is analysed in more detail, showing how the temperatures in the structure can be evaluated from meteorological data, temperature and solar radiation.
