ABSTRACT

ABSTRACT: This paper deals with the analysis of temperature records obtained for the orthotropic steel box girder of Millau viaduct crossing the Tarn valley in south of France. The analysis carried out by exploiting a series of records made over a period of 7 years from 2005 to 2011, helped to accurately know the thermal behavior of the deck, namely the evolution of extreme values of the average temperature of the box girder, values of thermal vertical and transversal gradients. It was also determined the correlation of these variables with meteorological data, temperature and solar radiation.
