Fatigue Life Assessment of Century Old Railway Bridge in India

Kishore Ch. Misra, Debojyoti Panda and Soumya Bhattacharjya

Fatigue life assessment of a century old railway bridge in India namely Jubilee bridge has been calculated following Eurocode 3 by using the Palmgren-Miner Rule. It has been observed that the remaining fatigue life of different members and bearings of the bridge has been exceeded in 2014 or on the verge of exceeding. Considering uncertainty and maintenance point of view the bridge, especially the outer bearing would be in more critical with respect to fatigue damage. Thus, it can be safely concluded that the bridge is no longer safe from fatigue point of view.
