Experimental Investigation of Fatigue Behavior of Tension Steel Plate Reinforced with Prestressed CFRP Laminates

  • To properly estimate the fatigue performances of a steel structure reinforced with prestressed CFRP(carbon fiber reinforcement polymer) plates,a modified Paris’ equation based on effective stress intensity factor range was presented to analyze the propagation of fatigue cracks.The effects of stress ratio,CFRP stiffness,prestress and adhesive property on fatigue crack growth were investigated through the fatigue tests of central cracked specimens.The experimental results show that the fatigue lives of reinforced specimens extend greatly,more than 16 times that of an un-reinforced specimen,and that their theoretically predicted results are more conservative than the experimental results.The prestress,rather than the properties of CFRP and adhesive,dominates the fatigue behavior of a reinforced specimen.The stress ratio plays a significant role in the fatigue life of a reinforced specimen.Therefore,the proper estimation of traffic loading is the foundation of effective reinforcement.
