Fatigue is one of the most often reasons for failure in existing steel railway bridges, particularly with riveted structure. Therefore fatigue assessment is always the most important part of the complex evaluation of existing steel railway bridges. Furthermore, the reliable fatigue assessment is often decisive in the estimation of the remaining service life of a bridge. The purpose of the presented research is a fatigue assessment of an 100 years old riveted truss railway bridge. The assessment was carried out to decide whether the existing truss superstructure is still suitable for rehabilitation in the frame of the ongoing modernization of the railway line. The fatigue assessment procedure is based on the safe life method in the convention of nominal stresses.
