“…In order to solve the construction problems of SRC composite structures, achieving the goal of avoiding the inconvenient procedure of forming rebar cages and improving the pouring quality of concrete, the steel and steel fiber reinforced concrete (SSFRC) structures are adapted by using steel fibers instead of rebar cages. In the existing literature, many scholars have confirmed the feasibility of using steel fibers to replace shear reinforcement bars or even rebar cages in reinforced concrete structures (Boita et al, 2017; Dinh et al, 2010; Ding et al, 2011; Ghazizadeh and Cruz-Noguez, 2018; Hung and Hu, 2018; Valipour et al, 2016; Yoo et al, 2017)…”

The interface slip between shape steel and concrete is one of the biggest problems in numerical simulation of composite structures, this paper aims to investigate interfacial bond-slip behavior between steel and steel fiber reinforced concrete. For this purpose, a series of push-out tests on 15 circular section specimens which were designed and fabricated with different steel fiber ratio, interface embedded length and concrete cover thickness have been done. Experimental results show that average bond strength versus free end slip curves of each specimen is similar, and then a basic average bond strength-free end slip constitutive model was proposed in this paper. Meanwhile, considering the distribution regularities of steel strains, local bond strength and relative slip along the interface embedded length at different load levels were obtained through the mechanical derivation, the results show that the maximum local bond strength was located near the free end, and the local bond strength away from free end tended to be steady. Based on the basic average bond strength-free end slip constitutive model, two position functions were proposed to describe the local bond-slip constitutive model considering the variation of positions. Two position functions are of great significance for further research on SSFRC non-linear properties by FEM.

“…Two low‐rise shear walls with the same geometry containing conventional concrete and FRC were tested by Ghazizadeh and Cruz‐Noguez 47 under the cyclic lateral loading. Although the SFRC wall was found to resemble conventional concrete in terms of strength, stiffness and ductility, its permanent displacement was significantly negligible.…”

Extensive damage to the bridges in recent earthquakes has revealed the vulnerability of these structures to the seismic excitation. Bridge piers play a key role in maintaining the operability of the bridge structure during and after earthquakes. As determinant elements in single‐pier bridges, wall piers significantly affect the bridge structure behavior. Hence, the present experimental study was conducted to examine the seismic performance of wall piers made of modern materials, that is, fiber reinforced concrete (FRC) in RC bridges. Eight wall piers made of steel fiber reinforced concrete (SFRC) with different aspect ratios, steel percentages and concrete strength were subjected to lateral load. The results showed that using SFRC reduced the steel strain within the serviceability range. Compared to conventional concrete, SFRC changes failure modes and deformational characteristics and also increases the energy dissipation capacity, stiffness in every drift values, load‐bearing capacity as well as yielding length.

“…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.
