“…To illustrate the prediction accuracy of ACI.440 equations, a comparison between ACI equation and experimental results is also made referring to the literature [8,[19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] including the experimental deflection-moment data of 91 concrete beams reinforced with FRP bars in the database collected, as in Table 4.…”

This paper presents an experimental study of the flexural defections of concrete beam reinforced with basalt FRP bars. Six concrete beams with different BFRP reinforcement ratio and one comparative beam reinforced with steel rebar are tested in laboratory. Numerical simulations using sectional analysis method and spatial FEM are performed. The experimental results can fit well with numerical simulation results. Analysis and experimental results in the literature collected indicate that the ACI-440.1R-06 equations underestimate the deflection of FRP-RC beams. Based on the experimental and numerical simulation results, a modified equation of the flexural rigidity is proposed to calculate the deflection of the FRP-RC beams. The proposed equation can fit better with the experimental results than the ACI-440.1R-06 equations.

“…The contribution of concrete under uniaxial compression was investigated using a nonlinear stress-strain relationship. The analytical study's obtained flexural capacity was compared to the findings of previously published experimental work [6] as well as the results derived using the ACI 440.1R-15 code [7]. The results showed that the predicted rupture modes by the analytical analysis matched the rupture modes seen in the experiment as recorded in Table 1.…”

Nowadays, several research concerns studying the behavior of FRP reinforcement in different structural members. FRP bars have numerous advantages that make them a good alternative to steel reinforcement, such as superior mechanical properties, non-corrosivity, sustainability, and a relatively higher stiffness-toweight ratio compared to steel reinforcement. FRP also has good fatigue characteristics, damage tolerance, nonmagnetic properties, simplicity of transportation and handling, and low energy consumption during manufacturing. This paper presents a general review of the behavior of concrete beams reinforced with different types of FRP. The effect of using the different types of FRP reinforcement on the behavior of reinforced concrete beams has been evaluated in terms of the ultimate capacity, deflection, cracking patterns, etc. In addition, this paper aims to evaluate the efficiency of using some techniques for strengthening reinforced concrete beams such as applying externally bonded CFPR or steel plates on the flexural and shear behavior of the tested beams.

“…The third method is the use of composite bars that can be an appropriate way to solve the problem of rebar corrosion [24,25]. These bars have acceptable properties, such as environmental durability and acceptable resistance to corrosion [6,[25][26][27][28][29][30][31][32][33]. However, the use of this method is limited due to the low modulus of elasticity of these bars [32,34,35].…”

One of the main disadvantages of steel bars is rebar corrosion, especially when they are exposed to aggressive environmental conditions such as marine environments. One of the suggested ways to solve this problem is to use composite bars. However, the use of these bars is ambiguous due to some weaknesses, such as low modulus of elasticity and linear behavior in the tensile tests. In this research, the effect of the hybridization process on mechanical behavior, including tensile strength, elastic modulus, and energy absorbed of composite bars, was evaluated. In addition, using basalt fibers because of their appropriate mechanical behavior, such as elastic modulus, tensile strength, durability, and high-temperature resistance, compared to glass fibers, as the main fibers in all types of composite hybrid bars, was investigated. A total of 12 hybrid composite bars were made in four different groups. Basalt and carbon T300 composite fibers, steel bars with a diameter of 6 mm, and steel wires with a diameter of 1.5 mm were used to fabricate hybrid composite bars, and vinyl ester 901 was used as the resin. The results show that, depending on composite fibers used for fabrication of hybrid composite bars, the modulus of elasticity and the tensile strength increased compared to glass-fiber-reinforced-polymer (GFRP) bars by 83% to 120% and 6% to 26%, respectively. Moreover, hybrid composite bars with basalt and steel wires witnessed higher absorbed energy compared to other types of hybrid composite bars.
