“…To simplify the calculation, only the aggregates with a diameter greater than 2.36 mm are simulated by drawing on the previous research experience [38,49,50], and it is assumed that smaller particles are mixed into the mortar. The same aggregate size distribution as Sadjad [51] and Wu et al [34] is adopted in this paper, as shown in Table 1.…”

“…[1][2][3] To overcome the brittleness and crack sensitivity of concrete, a large number of scholars have tried to enhance the mechanical properties of ordinary concrete with various fibers such as steel, polyvinyl alcohol (PVA), polyethylene (PE), and polypropylene (PP). 4 Fiber-reinforced concrete (FRC) is a multiphase heterogeneous cementitious material composed of cement, coarse and fine aggregates, and admixtures, reinforced with fiber materials. Compared to ordinary concrete (RC), it has higher ductility, strength, and durability.…”

“…The larger the crack width, the larger the contact area between the reinforcing steel and the unfavorable environment, promoting further corrosion of reinforcing steel, reinforced concrete (RC) structure, concrete section cracking, corrosion of reinforcing steel will significantly weaken the stiffness, ductility, and load‐bearing capacity of the structure, in the section cracking, rust serious structure, and even brittle failure, seriously affecting the performance and durability of the structure, and even cause unpredictable engineering accidents 1–3 . To overcome the brittleness and crack sensitivity of concrete, a large number of scholars have tried to enhance the mechanical properties of ordinary concrete with various fibers such as steel, polyvinyl alcohol (PVA), polyethylene (PE), and polypropylene (PP) 4 …”

“…Sun et al [ 36 ] concluded that increasing the content of BF could effectively increase the peak load and fracture energy of concrete from three-point flexural tests and numerical simulations of prefabricated notched beams. Naderi et al [ 37 ] demonstrated the fracture process of steel fiber-reinforced concrete during uniaxial tensile and compression based on the 3D mesoscale structural features of steel fiber-reinforced concrete, including fibers, aggregates, mortar, interfacial transition zones, and voids. The flexural test of the concrete beam was simulated by Khan [ 38 ] at the optimum fiber content (0.8% for steel and 0.1% for polypropylene fibers).…”
