In this paper the fatigue performance of steel structures retrofitted by using CFRP (Carbon Fibre Reinforced Polymer) plates is investigated. Fatigue tests were performed on unconditioned double sided reinforcement specimens (7 specimens) and on double sided shear lap joints (16 specimens). The stiffness degradation due to progressive debonding of the adhesive was selected as an index for the progressive global failure. Finally S-N curves were defined and compared to the fatigue resistance of welded detail categories of the Eurocode 3.

Abstract
In this paper the fatigue performance of steel structures retrofitted by using CFRP (Carbon Fibre Reinforced Polymer) plates is investigated. Fatigue tests were performed on unconditioned double sided reinforcement specimens (7 specimens) and on double sided shear lap joints (16 specimens). The stiffness degradation due to progressive debonding of the adhesive was selected as an index for the progressive global failure. Finally S-N curves were defined and compared to the fatigue resistance of welded detail categories of the Eurocode 3.File in questo prodotto:
