The conducted research consisted in static tensile strength tests of steel samples collected from the main girders of a railroad bridge that had been used for many years. It is estimated that it had been subjected to a load of approx. 160 000 trains during that time. Steel from bridge elements was used to construct bolted connections that were then subjected to static tensile strength tests. In order to compare the actual bearing capacity of the bolted connection constructed from bridge steel with the theoretical bearing capacity, a calculation model was created in the RFEM software.
