“…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.

“…Many kinds of dampers (hysteretic, viscous, viscoelastic, etc.) [61][62][63][64][65] are available on the market and can be embedded in the structure [66][67][68] or inserted between the structure to be retrofitted and an external reaction structure [69]. Dampers dissipate part of the input energy provided by the earthquake, thereby reducing the displacement demand of the structure.…”

Most European cities are characterized by very large areas, often formed by buildings of low quality, from a series of perspectives (architectural, technological, materials, technical systems, etc.). The possibility of renovating them is strategic to improve both the quality of life and to the possibility of economic recovery for building companies. In the last decades, the attention of the scientific community has been addressed to the energy renovation, thanks to the strong activities of the European Community in this field. However, since a relevant part of the EC territory is at risk of earthquake, the possibility to combine both energy and seismic renovation actions may be strategic for many countries. In particular, Italy and Romania are linked by a common social tradition that springs from the Roman Empire. Nowadays, this link is stronger, thanks to common interests in social, cultural and business fields. Therefore, the investigation of possible synergies for seismic and energy renovation strategies may be really interesting for both countries. In this paper, after an overview of regulations and common practices for buildings with reinforced concrete structures, in both states, some key combined renovation interventions will be described and discussed, as well as advantages and perspectives of integrated renovation approaches. The outcomes of this work are to show the way to transform existing energy-consuming and seismic-prone buildings into energy-efficient and seismic-resistant ones.

“…Both GFRPs (glass-fibre reinforced polymers) and CFRPs (carbon-fibre reinforced polymers) are currently being widely researched for strengthening and retrofitting steel structures [23,24,25,26,27,28,29,30,31]. Besides its strength and fatigue-life advantages, GFRP is lightweight, durable, and non-conductive to electricity/heat [32].…”
