Fatigue behavior of stiffener to cross beam joints in orthotropic steel decks Croce, Pietro Pellegrini, Daniele Orthotropic steel bridge decks Fatigue Stiffener to cross beams joints Cope hole J-integral Stress intensity factor info:eu-repo/classification/acm/J.2 PHYSICAL SCIENCES AND ENGINEERING In the paper the possibility to evaluate the fatigue strength of stiffener to cross beam joints in orthotropic steel decks is discussed. The proposed methodology, based on Paris-Erdogan law, allows to derive a sound estimate of the stress intensity factor K combining the indirect approach, based on the Rice J-integral, with the direct one, based on the extrapolation of experimental or numerical data. The practical implementation of the proposed methodology allowed to predict correctly the actual fatigue life of a previously tested real scale specimen, so validating its potentialities.
