This paper reviews Fibre Reinforced Polymer (FRP) composites in Civil Engineering applications. Three FRP types are used in Structural Engineering: FRP profiles for new construction, FRP rebars and FRP strengthening systems. Basic materials (fibres and resins), manufacturing processes and material properties are discussed. The focus of the paper is on all-FRP new-build structures and their joints. All-FRP structures use pultruded FRP profiles. Their connections and joints use bolting, bonding or a combination of both. For plate-to-pate connections, effects of geometry, fibre direction, type and rate of loading, bolt torque and bolt hole clearance, and washers on failure modes and strength are reviewed. FRP beam-columns joints are also reviewed. The joints are divided into five categories: web cleated, web and flange cleated, high strength, plate bolted and box profile joints. The effect of both static and cyclic loading on joints is studied. The joints’ failure modes are also discussed.

“…The design of GFRP-RC elements is expected to become more efficient following the publication of the second edition of AASHTO Bridge Design Specifications for GFRP Reinforced Concrete, approved in June 2018 [10]. Similarly, the design of CFRP-PC elements is expected to become more efficient following the publication of specific AASHTO design specifications, currently under development [11].…”

To support and promote the deployment of innovative technologies in infrastructure, it is fundamental to quantify their implications in terms of both economic and environmental impacts.Glass Fiber-Reinforced Polymer (GFRP) bars and Carbon Fiber-Reinforced Polymer (CFRP) strands are validated corrosion-resistant solutions for Reinforced Concrete (RC) and Prestressed Concrete (PC) structures. Studies on the performances of FRP reinforcement in seawater and saltcontaminated concrete have been conducted and show that the technology is a viable solution.Nevertheless, the economic and environmental implications of FRP-RC/PC deployment have not been fully investigated. This paper deals with the Life Cycle Cost (LCC) and Life Cycle Assessment (LCA) analyses of an FRP-RC/PC bridge in Florida. The bridge is designed to be entirely reinforced with FRP bars and strands and does not include any Carbon Steel (CS) reinforcement. Furthermore, the deployment of seawater concrete in some of the elements of the bridge is considered. LCC and LCA analyses at the design stage are performed. Data regarding equipment, labor rates, consumables, fuel consumption and disposal were collected during the construction phase and the analysis is refined accordingly. The FRP-RC/PC bridge design is

There are number of design guides produced in the USA as well, including 'ACI 440.1R-15: Guide for the Design and Construction of Structural Concrete Reinforced with Fiber-Reinforced Polymer (FRP) Bars' [33] and 'NCHRP research report 907: Design of Concrete Bridge Beams Prestressed with CFRP Systems' [53]. Recent research on FRP rebars, rods and cables is reported in the papers [54][55][56].…”

Construction produces a third of global carbon emissions. These emissions cause global warming and contribute to climate emergency. There is a need to encourage use of sustainable and eco-friendly materials to effectively deal with climate emergency. Fibre-reinforced polymer (FRP) is an eco-friendly material with low-carbon footprint. FRP composites in civil engineering are mainly used in three applications: (1) FRP profiles in new-build; (2) FRP-reinforcing bar in concrete members and (3) FRP in repair and rehabilitation of existing structures. This chapter presents basic properties of constituent materials (fibres and polymer resins), mechanical properties of FRP bars, strengthening systems and profiles, manufacturing processes and civil engineering applications of FRP composites. Durability, sustainability and recycling of FRP composites are also discussed.
