Thermal effects can have a significant impact on the durability of concrete bridges [4,5,6,7,8,9,10]. The research gives environmental effects as a cause of bridge failures. A review of the design standards and guidelines shows that more precise recommendations for sizing of reinforcement for thermal effects is needed. This paper focuses on the assessment of the influence of hot asphalt mixture laid on the deck on the stresses in a PT box girder at the construction stage. Results of FEA were confirmed by the research conducted on the structure in-situ and show a significant stress development in the girder at this stage. It is concluded that the existing code requirements need to be supplemented. |
