Fatigue failure of bridges occurs after repeated loading and unloading and hence fatigue becomes
more and more severe with time. A majority of all existing riveted bridges are not explicitly
designed for fatigue failures. Bridge owners should therefore have focus on fatigue life of riveted
bridges. It can be difficult to discover fatigue cracks by visual inspection due to thick layers of paint
and the fact that the rivets themselves may hide the cracks. Hence, it may be necessary to
determine critical joints and possible fatigue cracks by using FE-modelling. Identification of critical
joints may also target future inspection efforts and highlight hidden details, which may call for
special inspection measures to be implemented. This paper describes a fatigue study of 11 riveted
railway bridges in Denmark that includes both visual inspections and FE-modelling of bridges.
