“…Kim and Hefferan (2008) and Oudah and El-Hacha (2013) produced two comprehensive reviews of the fatigue behaviours of RC beams flexurally strengthened with FRP laminates. The fatigue failure process of FRP-strengthened beams can usually be described in three stages: cracks initiation, stable damage, and unstable failure (Xie et al 2012). In generally, the first phase covers about 3% to 5% of the fatigue life.…”

Many concrete structures are vulnerable to extreme loadings such as accidental impact, terrorist attack and earthquake disasters. Retrofitting of existing concrete structures for enhanced performance under these loadings has been an important topic of research for a long time, especially since the 911 terrorist attack. Among the different retrofitting techniques, external bonding of fibre reinforced polymer (FRP) composites has been a popular one. This paper presents a brief review of recent research on FRP strengthened concrete structures under blast, impact, earthquake and cyclic loading.

“…The second stage covers about 90% of the fatigue life during which little change in the deformation of the beam is experienced. The third stage is a rapid failure stage, in which the tensile steel fractures first followed by FRP debonding or rupture (Xie et al 2012).…”

“…To validate the proposed model, an experimental database consisting of 28 prestressed/non-prestressed FRP sheets strengthened RC beams (Barnes et al 1999;Papakonstantinou et al 2001;Heffernan et al 2004;Quattlebaum et al 2005;Toutanji et al 2006;Yu et al 2011;Xie et al 2012) was established. All beams were reported to have failed with the rupture of tensile steel reinforcement.…”

Based on the failed criterion of steel reinforcement fracture, an analytical model is presented for predicting the fatigue life of reinforced concrete (RC) beam strengthened with fiber reinforced polymer (FRP) sheets. In this model, the load cycle is divided into some loading blocks evenly and the stress amplitude of the tensile steel reinforcement is thought to be invariable in each loading block. Considering the degradation of material performance, including concrete creep, the stress amplitude of the tensile steel reinforcement is obtained by using the traditional sectional analysis method. Therefore, the fatigue life of the strengthened beam is carried out by using the well-known Palmgren-Miner rule. The reliability of the proposed analytical model is validated through comparisons with previous test results reported by the relative research groups. The compared results show that the proposed models can predict the fatigue life of the strengthened beam with an acceptable degree of accuracy.

“…For example, Zhang et al [8] observed on the partially PC beams with corroded rebars and found out that the fatigue life of the beams decreases and the rate of the stiffness degradation and the midspan deflection development grows with the corrosion ratio increasing. Additionally, the researchers conducted other investigations on the partially PC beams and drew some conclusions such that [9][10][11][12][13][14] the fatigue failure of the beams begins from the fatigue fracture of the rebar at the bottom, which determines the fatigue life of the beams and the maximum midspan deflection increased by 10%~20% to failure than that in the initial case and so forth. Furthermore, according to the investigation on the fatigue performance deterioration of the heavy-haul railway bridges, firstly, an S-N model [15] is developed considering the rebar stress range-fatigue life relationship and stress ratio (the ratio of initial stress range to stress range to failure)-and fatigue life relationship, by observing the scale model of bridges under fatigue loading.…”

“…As an essential method, the experimental investigations in the literature are generally able to be concluded in the following three aspects: the investigation on the fatigue performance deterioration of the reinforced concrete (RC) beams or strengthened RC beams [4][5][6][7], the investigation on that of the partially prestressed concrete (PC) beams [8][9][10][11][12][13][14], and the investigation on that of the heavy-haul railway bridges [15][16][17]. For example, Zhang et al [8] observed on the partially PC beams with corroded rebars and found out that the fatigue life of the beams decreases and the rate of the stiffness degradation and the midspan deflection development grows with the corrosion ratio increasing.…”

Heavy-haul railway bridges play an increasingly essential role in the transportation in China due to the increasing transport volume. The performance deterioration of the scale models of a typical heavy-haul railway bridge under fatigue loading is monitored in this work, based on a multisensor system including the fiber-reinforced polymer optical fiber Bragg grating and electrical resistance strain gauges, linear variable displacement transducer, and accelerometer. Specifically, by monitoring/ observing on the failure mode, fatigue life, load-midspan deflection response, material strain development, and so forth, this work develops an S-N model by comparing the relationship between fatigue life and rebar stress range with that between fatigue life and load level and proposes a damage evolution model considering the coupling of the stiffness degradation and inelastic deformation of specimens. It is found that the fatigue life of specimens is determined by the fatigue life of the rebar at the bottom and it may be lower than 2.0 million cycles with a 30-ton axle weight when environmental factors are taken into account. The predictions of the models agree well with experimental results. Therefore, this work furthers the understanding of the fatigue performance deterioration of the bridges by using a multisensor system.
