Abstract [en]

The aim of this work is to calculate partial coefficients for thermal cracking problems of young concrete and to compare the results with the values stated in the Swedish building code for bridges, [1]. The code values are only based on experiences and logical reasoning, whereas the calculated values form a more theoretical base for their determination. The coefficients are calculated with a probabilistic method. Various different possible variations of the used variables have been studied showing the wide range of possible results depending on the input. However, with use of material properties and reasonable assumptions related to thermal cracking problems, fairly good agreement has been found between the stated values in the Swedish code [1] and the values obtained through the probabilistic method. The calculated values are based on many assumptions and assumed values and should therefor not be seen as what is right but rather more as an indication on the reasonableness of the values stated in the Swedish code. Further investigations, calculations and judgements should be performed before wider conclusions can be drawn.
