“…The investigated parameters varied and included the sectional configuration, the type of the three constituent materials, the slenderness ratio, and the load eccentricity. On the other hand, the concept of FCSRC systems has been applied to the buckling restrained braces (BRBs) that are commonly used as passive energy dissipation devices in seismic zones (i.e., stabilizing steel braces with FRP reinforcements) [58][59][60][61][62][63][64][65][66][67][68]. As shown in Figure 6, in such a form of BRBs, FRP composites are often used as the external shell, which can provide confinement to improve the buckling behavior and ultimate strength of the steel core.…”

“…Recently, FRP composites with high stiffness have been adopted to prevent the local and overall buckling failure of slender steel members [58,[96][97][98]. Many efforts have been made to apply the concept of FCSRC systems in BRBs for structural repairing [58][59][60][61][62][63][64][65][66][67][68].As shown in Table 2, previous studies on FCSRC BRBs have focused on behavior under axial compression or reversed cyclic loading. The studied parameters included variables of the…”

“…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.

“…While structures made of conventional materials may exhibit some postyield stiffness (usually less than 10% of the initial stiffness), the application of new materials with high strength and superior elastic properties can easily be used to develop structures with a much higher and more stable postyield stiffness. These high‐strength elastic materials, such as fiber‐reinforced polymer (FRP) and high‐strength steel bars, exhibit little or approximately no plastic behavior and have been recently used to fabricate many novel materials, members, and structures. Compared with the components made of only conventional materials (steel and concrete), increasingly more materials, members, and structures that incorporate both high‐strength elastic materials and conventional materials show significant postyield hardening (PYH) skeleton curves (Figure ).…”

It is widely accepted that ductility design improves the seismic capacity of structures worldwide. Nevertheless, inelastic deformation allows serious damage to occur in structures. Previous studies have shown that a certain level of postyield stiffness may reduce both the peak displacement and residual deformation of a structure. In recent years, several high-strength elastic materials, such as fiber-reinforced polymer (FRP) and high-strength steel bars, have been developed. Application of these materials can easily provide a structure with a much higher and more stable postyield stiffness. Many materials, members, and structures that incorporate both high-strength elastic materials and conventional materials show significant postyield hardening (PYH) behaviors.The significant postyield stiffness of PYH structures can help effectively reduce both peak and residual deformations, providing a choice when designing resilient structures. However, the findings of previous studies of structures with elastic-perfectly plastic (EPP) behavior or small postyield stiffness may not be accurate for PYH structures. The postyield stiffness of a structure must be considered an important primary structural parameter, in addition to initial stiffness, yielding strength, and ductility. In this paper, extensive time history and statistical analyses are carried out for PYH single-degree-of-freedom (SDOF) systems. The mean values and coefficients of variation of the peak displacement and residual deformation are obtained and discussed. A new R-μ p -T-α relationship and damage index for PYH structures are proposed. A theoretical model for the calculation of residual deformation is also established. These models provide a basis for developing the appropriate seismic design and performance evaluation procedures for PYH structures.KEYWORDS damage index, high-strength elastic materials, peak displacement, postyield stiffness, residual deformation, single degree of freedom
