Abstrait:

For fatigue assessments of railway bridges improved load spectra are given in EN1991-2. This could have relevant consequences on design of new bridges as well as on the evaluation of residual fatigue life of existing bridges. As known, beside explicit damage calculations, fatigue can be assessed using the so-calledλmethod. In the study, the accuracy of damage equivalence factorsλgiven in EN1993-2 for railway steel bridges is discussed, pointing out that their values need some refinement, also in view of future improvements of the EN1993-2 itself.
