【 摘 要 】

The fatigue strength of the characteristic details of road bridges by Eurocode 3 has been analysed in this paper. Verification of fatigue resistance has carried out by two different methods, recommended by SRPS EN 1993-1-9, the method of damage equivalent factor and the damage accumulation method. The action effects in characteristic details were calculated using load models defined in appropriate standards. Beside of stress range, fatigue effects are defined by stress frequency during designed lifetime of construction. Fatigue verification by method of equivalent damage factor has been performed using the detail categories defined in SRPS EN 199-1-9, while fatigue verification according to damage accumulation method has been performed using the Miner's accumulation curve. Comparison of results obtained by these two methods has been pressented at the end of the paper, using the concept of equivalent stress.
