Abstract: Majority of the railway bridges are under study as they are facing the risk of their service life completion. The present study describes the importance of the residual fatigue life available for a truss bridge. The modeling and analytical work was done using TEKLA Structures 17.0. The analytical interpretation of the stress range of the model with the load cycles taken by the structure were co-related to obtain the necessary parameters. The most common method used is Miner’s damage contribution. The effect due to variation of loading amplitude is approximated by means of deterministic approach. Finally the obtained results will be compared with the BS-5400.
