Fatigue is the effect of alternating stresses acting for a long time over structural members. Such phenomenon is very common in bridges. In one passage of vehicle, generated stress may be very small but its cumulative effect will reduce the life span of the structure. In the present study fatigue life estimation of steel arch bridge with various hanger arrangements has been studied considering the passage IRC 70 vehicles. Finite Element Model of the steel arch bridge has been created in SAP2000 and stresses in the vulnerable members have been determined for different velocity of the vehicle. The approach is based on Miner’s hypothesis of damage accumulation
