“…Upon service temperatures above the T g value, the adhesive changes from a solid to a viscous state, resulting in a loss of strength and stiffness. Such bonding adhesive property degradations impair the bond behaviour of the interface, resulting in the stress transfer loss between materials and the early debonding failure of the FRP laminate [ 66 , 67 , 68 ]. The second effect (thermal stress effect), on the other hand, is primarily associated with the fact that the concrete and the FRP laminate have different thermal expansion coefficients (CTEs).…”

Several experimental and numerical studies have been conducted to address the structural performance of FRP-reinforced/strengthened concrete structures under and after exposure to elevated temperatures. The present paper reviews over 100 research studies focused on the structural responses of different FRP-reinforced/strengthened concrete structures after exposure to elevated temperatures, ranging from ambient temperatures to flame. Different structural systems were considered, including FRP laminate bonded to concrete, FRP-reinforced concrete, FRP-wrapped concrete, and concrete-filled FRP tubes. According to the reported data, it is generally accepted that, in the case of insignificant resin in the post curing process, as the temperature increases, the ultimate strength, bond strength, and structure stiffness reduce, especially when the glass transition temperature Tg of the resin is approached and exceeded. However, in the case of post curing, resin appears to preserve its mechanical properties at high temperatures, which results in the appropriate structural performance of FRP-reinforced/strengthened members at high temperatures that are below the resin decomposition temperature Td. Given the research gaps, recommendations for future studies have been presented. The discussions, findings, and comparisons presented in this review paper will help designers and researchers to better understand the performance of concrete structures that are reinforced/strengthened with FRPs under elevated temperatures and consider appropriate approaches when designing such structures.

“…Especially in corrosive environments, FRP composites form an attractive alternative to traditional steel reinforcement, owing to their high corrosion resistance [10,[51][52][53]. Furthermore, fibres can be oriented [54] to give desirable mechanical properties in circumferential and longitudinal directions in FRP composites [2,55]. It is worth mentioning that vulnerability to elevated temperatures [56][57][58], low shear strength and ductility [1] are some of the FRP drawbacks that hinder their wide usage in specific applications.…”

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.

“…Therefore, the durability of composite-reinforced concrete structures in harsh environmental conditions (e.g. alkaline, acidic, and marine environments as well as elevated temperatures) has always been a major concern [33,96,118,[123][124][125][126][127][128]. The U.S. allocates more than $1 billion annually for repairing and replacing waterfront piling systems [8].…”
