Abstract

The purpose of this paper is to provide realistic values of extreme thermal loads applicable to composite box girder bridges on the basis of the statistical analysis of long-term measured temperature data. For this purpose, temperatures were recorded at a newly constructed composite box girder bridge for about 6 years. Before analyzing the extreme values, major thermal loading parameters that characterize the temperature profile are defined. The limit distributions of the thermal loading parameters are then determined by the tail-equivalence method, and the thermal loading parameters corresponding to selected return periods are calculated. Finally, the results are compared to the specifications suggested in a current design code for thermal loads.
