“…In practical engineering, many structures, such as highway and railway bridges, airport pavements, and offshore elements, are continuously subjected to cyclic loads during their service life, such as traffic loads, wind loads, and seismic loads [ 42 , 43 ]. To date, studies regarding BFRP-RC structures reinforced with or without fibers under monotonic loading have been widely conducted and published [ 12 , 13 , 19 , 20 , 24 , 36 ].…”

This research investigated the flexural behavior of high-strength concrete beams reinforced with continuous basalt fiber-reinforced polymer (BFRP) bars and discrete steel fibers. Five concrete beams with the dimensions of 150 × 300 × 2100 mm3 were constructed and tested to failure under four-point bending cyclic loading. The specimens consisted of four BFRP-reinforced concrete beams with various reinforcement ratios (ρf), namely, 0.56%, 0.77%, 1.15%, and 1.65%, and one conventional steel-reinforced concrete beam for comparison purposes. The cracking behavior, failure modes, load-deflection behavior, residual deformation, and stiffness degradation of the beams were studied. Additionally, a deformation-based approach was used to analyze the deformability of the beams. The results show that an increase in the ρf effectively restrained the crack widths, deflections, and residual deformation while also enhancing the flexural bearing capacity of the beams. In comparison to the first displacement cycle, the bearing capacity dropped by 10% on average in the third cycle. The stiffness exhibited a fast to slow degradation trend until failure. The residual stiffnesses were higher in beams with a higher ρf. The over-reinforced beams had superior deformability than the under-reinforced beams, according to the deformability factors.

“…This phenomenon is particularly evident in C-9, which has the highest corrosion, as shown in Figure 6C. The main reason for the difference in failure modes between the corrosion and fatigue specimens is that the cyclic loading causes the concrete before the cross ribs of the reinforced bar to be crushed (Shen et al, 2020). However, the expansion effect of corrosion products in the corrosion specimens makes the concrete produce microcracks on the interface of the reinforced bar and the concrete.…”

Corrosion of reinforced bars and the fatigue effect in concrete structures significantly impact the bond performance of reinforced bars. The current research mainly focuses on the effect of fatigue or corrosion on the bonding properties of steel bars, which is still quite different from the service environment of the structure. The degradation law of the bond performance, failure characteristics, and changing trend of bond stress along the anchorage length of reinforced concrete specimens were analyzed under the combined action of fatigue and corrosion in this test. Under the combined action of corrosion and fatigue, the specimens’ bond stress and slip limit are significantly reduced, and the steel bars may fracture during the loading process. There are two peaks in the longitudinal distribution curve of the combined stress of the specimen under the combined action of fatigue and corrosion.

“…Research has shown that this can lead to a significant reduction in bond strength for steel and concrete composites [46,47]. Furthermore, studies conducted on the bond behaviour of concrete reinforced with FRP bars have shown that cyclic load can cause significant bond deterioration, increase in slip and reduction in energy dissipation compared to an identical monotonically loaded sample [66][67][68].…”

Using fibre-reinforced polymers (FRP) in construction avoids corrosion issues associated with the use of traditional steel reinforcement, while seawater and sea sand concrete (SWSSC) reduces environmental issues and resource shortages caused by the production of traditional concrete. The paper gives an overview of the current research on the bond performance between FRP tube and concrete with particular focus on SWSSC. The review follows a thematic broad-to-narrow approach. It reflects on the current research around the significance and application of FRP and SWSSC and discusses important issues around the bond strength and cyclic behaviour of tubular composites. A review of recent studies of bond strength between FRP and concrete and steel and concrete under static or cyclic loading using pushout tests is presented. In addition, the influence of different parameters on the pushout test results are summarised. Finally, recommendations for future studies are proposed.
