Abstract

This report contains the results of the research work carried out by the Italian group within the collective programme on the fatigue strength of orthotropic decks of steel bridges, in the third phase of the general research programme "Measurements and interpretation of dynamical loads on bridges". The research concerned the theoretical study of the static behaviour of orthotropic decks of steel bridges, with the aim of calculating the normal stresses induced by wheel loads in the points of the deck most sensitive to fatigue cracking risk. The accuracy of the theoretical results has been successfully verified with static tests performed on a full-scale deck specimen. In addition, experimental investigations have been carried out to determine the S-N curve related to two widely used connection typologies between stiffeners. Tests have been performed both on full-scale rib specimens and on large pieces of orthotropic steel decks.
