摘要
In this paper the results from three different types of tests performed will be discussed. All of the construction details are pare of KB5/Fast Bridge 48. This is a new type of rapid assembled military bridge constructed by Karlskronavarvet. The performed tests all concern the low cycle fatigue behaviour in extra high strength steel, EHS, and ultra high strength steel, UHS. Since these steels are relatively new products there are no design codes available for these steels and therefore design through testing must be performed. Since these applications are from real structures there are no corresponding detail classes in the codes. The results from these tests shows that the current design codes for fatigue can be used and the codes will give fatigue strength well on the safe side.
