    Abstract
  • Aged steel bridges are prone to fatigue cracking, which is a challenging problem for the safety of bridges during their service. An experimental and theoretical study was conducted to improve the fatigue performance of notched steel beams strengthened with prestressed unbounded carbon-fibre-reinforced polymer (CFRP) plates. The Paris law was used to obtain the S-N curve of the reinforced steel beam, and the effect of the prestress level on the fatigue life was presented. Double-edge-notched large-scale specimens were strengthened using an unbonded CFRP plate with different prestressing levels and were thereafter tested under cyclic loading. Experimental results show that prestress reduces both the crack growth rate and stiffness decay of the specimens by up to 40%, and thus, the fatigue life is extended by more than three times. The specimen with the highest prestress level exhibits the best performance, extending the fatigue life by more than eight times. Moreover, prestressed CFRP reinforcements upgrade the fatigue category of the notched beam from 51 MPa to 75 MPa. The theoretically predicted results are reasonably consistent with the experimental results, and the proposed method is recommended for lifetime evaluations of components.
