“…SRCW systems include different typologies, e.g. RC walls with encased steel profiles [10], RC walls with steel plates enhanced with concrete-filled steel tubes [11], prefabricated concrete-filled steel tubular framework composite slabs [12], RC walls with steel plates [13], use innovative materials in order to strengthen the RC infill walls of the hybrid systems [14], [15] and steel frames with RC infill walls [3], [16].…”

Hybrid steel and concrete seismic‐resistant systems made by steel frames with reinforced concrete infill walls (SRCWs) have potential advantages over structural solutions made only by steel or reinforced concrete (RC). In fact, the high initial stiffness of concrete is useful to minimize the damage of non‐structural elements under frequent (low to moderate) earthquakes while the ductility and dissipative capacity of the steel allow good performances under rare (high‐intensity) events. Eurocode 8 considers SRCW systems to behave essentially as RC walls. However, numerical analyses on SRCWs, designed according to the Eurocodes, pointed out an unsatisfactory seismic behaviour with discrepancies between the behaviour assumed in the design and the simulated response under seismic actions. Indeed, the idea of stiffening a steel frame with a RC infill leads complex mechanisms that are difficult to control as being affected by many variables. In this study, some of the recent developments made for innovative SRCW are transferred to hybrid steel and concrete walls with partially‐prefabricated infills. Numerical models are analysed to understand the global behaviour of the considered SRCWs and to provide a preliminary validation of the proposed structural solution.

“…Glass fiber-reinforced polymer (GFRP) material has properties such as high strength-to-weight ratio, high corrosion resistance and low maintenance, and ease of fabrication. As a result, GFRP-based materials can handle high structural load, increase the durability, serve as an excellent cost-effective repair material, and thus is a great alternative to conventional materials [3][4][5][8][9][10][11][12]. e commercially viable products manufactured using GFRP include mostly automotive parts, bathtubs, printed circuit boards, boats, and aerospace components.…”

“…FRC or GFRP fabricated sheets are retrofitted on beams, columns, and slabs to prevent the structure against corrosion as well as enhancing its longevity [21]. Fibers that have been successfully used in improving the strength and longevity of concrete infrastructures are glass [1,7,10,11,18,22,23], steel [1,10,11,14,15,17,24], carbon fibers [24][25][26][27][28], and polypropylene fibers [13,15,17,29]. In particular, flexural and shrinkage properties have shown significant improvements with the addition of fibers in cement [16,18,22,30].…”

Fiber-reinforced concrete (FRC) and engineered cementitious composite materials have demonstrated promising requisite in construction industry owing to its superior mechanical and durability properties. In this study, a sustainable approach was taken, i.e., to use industry waste as a reinforcement with improved interfacial bonding leading to enhanced mechanical performance of FRC. An efficient in situ recycling process allowed the authors to extract glass fibers from glass fiber-reinforced polymer acrylic waste. Concrete mixes with low fiber dosages including 0.1%, 0.2%, and 0.3% (by volume) of recycled as well as virgin glass fibers were prepared. The slump of concrete was maintained ∼150 mm by using high water-reducing admixture (HWRA). Notably, lower amount of HWRA was required for raw glass fibers vis-à-vis recycled ones due to its hydrophobic nature. Overall, FRC enclosing 0.3% recycled glass fiber demonstrated >20% enhancement in compressive, split tensile, and flexural strength as compared to control (after 28 days of curing), also supported by morphological analysis.
