“…I-shaped (or H-shaped) steel sections are one of the most common forms in steel structures, and they have recently been used in FCSRC columns (see Figure 7) [32,34,35,[37][38][39][40][41]43,[46][47][48]50,52,53,55,56]. Previous studies on FRP-confined concrete-encased I-section steel columns have indicated their excellent ductility under various loading scenarios (e.g., concentric compression and eccentric compression).…”

“…Yu et al [50] reported that a combination of the three constituent materials (i.e., FRP, concrete, and steel) in this form of hybrid system achieved beneficial interactions between them (see Figure 8b). In addition, longitudinal reinforcing bars have sometimes been embedded to compensate for the loss of the weak-axis bending stiffness and increase the capacity of corroded and buckled steel columns [52,55].…”

(a) In most cases, I-or H-shaped steel columns are fully encased by the concrete and the composite columns are fully confined by an FRP jacket along with the column height [32,[36][37][38][39][40][41]43,47,48,50,52,53,55,56].…”

“…Up to date, FCSRC systems have been adopted to strengthen/repair steel structures [32][33][34][35][36]52,55] and as new hybrid structural members (e.g., hybrid columns, beams [37][38][39][40][41][42][43][44][45][46][47][48][49][50][51]53,54,56,57], or buckling restrained braces (BRBs) [58][59][60][61][62][63][64][65][66][67][68]). Extensive studies have been carried out to understand the performance of such forms of hybrid structural members, and they have been shown to have excellent performance.…”

Fiber-reinforced polymer (FRP) composites have been widely used for strengthening or constructing structures due to their excellent corrosion resistance and high tensile strength. An emerging hybrid structural member form with FRP composites—which consist of a steel section as internal reinforcement, an external FRP wrap/tube, and concrete filled between them (referred to as FRP-confined steel-reinforced concrete systems (FCSRC) systems)—has attracted increasing research interest. To date, the concept has been adopted to strengthen/repair steel structures or used as new hybrid structural members (e.g., hybrid columns or beams, including buckling restrained braces (BRBs)). The FRP confinement and composite action between the three components in FCSRCs result in the excellent performance of the hybrid member. This paper presents a state-of-the-art review of FCSRCs for structural applications. The gaps in knowledge and future research opportunities on FCSRC structural members are also identified.

“…Various repair techniques such as fiber-reinforced polymer jacket ( 5 – 7 ), concrete-filled pultruded fiber-reinforced polymer tubes ( 8 ), and steel plates ( 9 ) have been used by many Departments of Transportation (DOTs) in the U.S. to restore the carrying capacity of corroded piles, based on the level of corrosion and targeted performance objective of the corroded piles. Another cost-effective repair technique is concrete encasement, in which the corroded region of the steel pile is encased in a concrete jacket ( 10 , 11 ).…”

Steel H-piles have been used widely in bridge construction throughout the U.S. because of their relatively large load-carrying capacity while occupying a small area. However, many H-piles suffer from corrosion, which may lead to abrupt collapse. A cost-effective repair technique, including encasing the corroded region of the steel pile into a concrete jacket, which acts as an alternative load path for the applied axial load, has been used by several state Departments of Transportation. Methyl methacrylate polymer concrete (MMA-PC) is a type of concrete that is commonly used as a repair material. However, there is limited research on the assessment of bond strength between MMA-PC and steel elements. This paper investigates experimentally the bond behavior of seven full-scale steel H-piles encased in concrete jackets. The jackets were cast using either MMA-PC or Portland cement concrete (CC). Different embedment lengths of 63.5 mm (2.5 in.), 127 mm (5 in.), and 190.5 mm (7.5 in.) were used for the MMA-PC and one embedment length of 254 mm (10 in.) was used for the CC jacket. Cylindrical and prismatic jacket configurations were used and tested using push-out. The experimental results revealed that using the MMA-PC jacket was more effective compared with the CC jacket in relation to the load-carrying capacity. For design purposes, a shear bond stress of 2.96 MPa [0.43 kips per square inch (ksi)] can be used for MMA-PC jackets having an embedment length of at least 127 mm (5 in.) whereas a value of 0.83 MPa (0.12 ksi) can be used for CC.
