“…Among a few publications, Miere [1] , Inoue [4] , Barnes [5] , Hefferna [6] , E. Ferrier [7] et al have studied experimentally on the fatigue behavior of the whole strengthened beams. The results of these studies showed that the fatigue life can be increased effectively by strengthening with FRP [1][2][3][4][5][6][7][8] . However, very limited research on bond behavior under cyclic fatigue loading of concrete structures strengthened with FRP has been reported.…”

Peeling along the interface between FRP and concrete under fatigue load is the common failure pattern for the RC structures strengthened with FRP. In this paper, five groups specimens were subjected to fatigue load to study the fatigue mechanism for bonding interface between carbon fiber laminate (CFL) and concrete. The Δσ~N curves for the bonding interface were derived from the experiments, the laws of strains and slip on interface were analyzed in this paper.

“…Fatigue performance and durability of reinforced concrete (RC) beams strengthened with fibre reinforced polymer (FRP) are of great concern in the field of civil engineering 1–8 . For the fatigue behaviour research of RC beams strengthened with FRP, verification experimental studies of fatigue behaviours of carbon fibre reinforced polymer (CFRP) or RC components strengthened with CFRP have been carried out since last mid‐nineties 1–5 . Research results indicated that CFRP sheets largely improved the fatigue lives of RC beams.…”

“…Among them Miere 1 discussed the fatigue behaviour of RC components strengthened with glass fibre reinforced polymer (GFRP) and CFRP and proposed that GFRP and CFRP largely improved the fatigue behaviour of RC components. Inoue 2 carried out fatigue tests of RC beams strengthened with CFRP and discovered that CFRP not only effectively improved the fatigue behaviour of RC beams but also decreased the deflection of mid‐span and the crack width of test beam. Muszynski and Sierakowski 3 got S–N curve from experimental study of RC beams strengthened with CFRP.…”

A B S T R A C T Fatigue performance of reinforced concrete (RC) components strengthened with fibre reinforced polymer (FRP) is largely improved. However, temperature changes of service environment have a great effect on the fatigue behaviour of RC components strengthened with FRP. Concerning about temperature variations in subtropical areas such as South China, this paper analyses the fatigue behaviour of RC beams strengthened with carbon fibre laminate (CFL) from experimental studies and theoretical analysis under four different temperatures (5 • C, 20 • C, 50 • C, 80 • C) and five different stress levels (0.60, 0.66, 0.72, 0.78, 0.84). The paper discusses temperature fatigue behaviour of RC beams strengthened with CFL under cyclic bending loads in different service environments, and proposes a calculation formula of fatigue lives of RC beams strengthened with CFL under environmental temperatures and external forces coupling. Experimental results show that the formula not only effectively predicts the fatigue lives of the RC beams strengthened with CFL under environmental temperatures and bending loads coupling but also estimates the fatigue limits.

“…However, bridge structures bear the action of fatigue loads, the fatigue bond strength between CFRP and concrete determines directly the structure safety. So, it is very important to carry out study on fatigue property of interfacial bond between concrete and CFRP, but research in this field was relatively poor, Inoue 9 , Toutanji 10 , Heffernan 11 , Mohsen 12 , simulated fatigue behavior of bond strength between CFRP and concrete by establishing analytical model. Yao Guo-wen carried out fatigue tests in RC beams with constant amplitude load, and established the damage accumulation model which could describe member damage and fracture process 13 .…”

The interfacial bond strength between carbon fiber reinforced polymers (CFRP) and concrete is a very important factor for the strengthening effect of CFRP. According to the test, the change law of shear stress and the damage process of epoxy bond are investigated under static and fatigue load in the paper. At the same time, the analytical calculation models of interfacial shear stress and strain at arbitrary points are established, therefore the static and fatigue bond strength can be calculated by the analytical models. Contrasting analysis indicates that the results of calculation models coincide with the tests, which shows that the results of analytical models are favorable. Moreover the model can also be used to analyze and predict the interfacial stress of the composite structure. It is also applicable for the other composite structures, which suggests that this method possesses practical significance for the reliability analysis of the interfacial bond strength.
