Croce P., Pellegrini D. Fatigue behavior of stiffener to cross beam joints in orthotropic steel decks. In: Procedia Engineering, vol. 101 pp. 101 - 108. Special issue: 3rd International Conference on Material and Component Performance under Variable Amplitude Loading, VAL2015. Czech Society for Mechanics (ed.). Elsevier, 2015.
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.
