| Summary: |
| 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 outbytwo
different methods, recommended bySRPS EN1993-1-9, the methodof damage equivalent
factorandthe damage accumulationmethod.The actioneffects incharacteristic details
were calculatedusing load models defined inappropriate standards. Beside of stress
range,fatigue effects are defined bystress frequency during designed lifetime of
construction. Fatigue verificationbymethod of equivalent damage factor has been
performed using the detail categories defined in SRPSEN199-1-9, while fatigue
verification according to damage accumulation methodhas beenperformed using the
Miner’s accumulationcurve. Comparisonofresults obtained bythese two methods
has beenpressented at the end of the paper,using theconcept ofequivalent stress. |
