FATIGUE TESTS ON THE OLD STRINGERS OF THE RAILWAY BRIDGES

Abstract

Both elements in one of the sections of the stringers of the Southern Railway Bridge in Budapest were replaced. With the use of the removed stringers, as well as those of another railway bridge closed to traffic, laboratory experiments were conducted. In their course fatigue test of the basic steel material was performed by the step method using specimens cut out of different places of the longitudinal girder. which was followed by the fatigue test performed on one of the complete on-stringers of the Southern Railway Bridge. The results are reported in this paper.
