Visual inspection reveals compliance issues in a steel riveted bridge over the Danube River, suggesting further evaluation is needed.
In the present publication, a railway approach viaduct, part of a steel riveted bridge over the Danube River in the town of Ruse, Bulgaria is considered. The bridge is built in 1952-1954 and is in operation. The results of a visual inspection of the structure are described and calculation checks were carried out in accordance with the old Bulgarian standards and European codes. For some critical elements, the fatigue life has been investigated. Conclusions have been made regarding problematic issues related to the compliance of the existing construction with the present requirements.
