“…El-Mogy et al [10,11] presented an experimental and a finite element study on the flexural behavior of continuous FRP-reinforced concrete beams. El-Mogy et al [12] concluded that deflection can be decreased when increasing the transverse GFRP reinforcement in continuous concrete beams inspite of keeping the longitudinal reinforcement the same. Chitsazan et al [13] studied experimentally the enhancement of the flexural behavior of concrete beams with GFRP bars by using high strength concrete and increasing the effective depth over the breadth of the beam.…”

This paper presents a nonlinear finite element model to investigate the behavior of hybrid Fiber Reinforced Polymers and steel reinforcement. Different types of Fiber Reinforced Polymers; CFRP and GFRP; were used along with steel rebars in the studied concrete beams. The study was conducted using the nonlinear finite element program ''ANSYS". Nonlinear material models for the components of the concrete beam were used in the three dimensional finite element models. The outcomes got from finite element analysis were confirmed against experimental results. A broad parametric study was conducted to explore the effect of replacing steel reinforcement by different types of FRP bars. The study showed that the contribution of steel rebars to FRP rebars in concrete beams improved beam ductility and eliminated the unfavorable brittle failure of the concrete beam. In addition, it is better to use steel rebars as top reinforcement in concrete beams with hybrid reinforcement. In hybrid GFRP/steel reinforced concrete beams, a significant reduction in stiffness and a noticeable increase in the beams' deflection after the initiation of first crack and yielding of steel reinforcement were observed. On the other hand, in hybrid CFRP/steel reinforced concrete beams showed a better performance during cracking initiation and propagation.

“…It was concluded that the basic parameter of increasing the load capacity of continuous beams was the amount of CFRP reinforcement in the bottom zone in the midspan. Other recent research studies on continuous beams [3,17,18,20] also pointed out to the importance of increasing the reinforcement in the bottom zone of the beam midspan, as a result of redistribution of moment over the middle support. e approach that in continuous beams reinforced with FRP reinforcement, moment redistribution in critical sections is not allowed could be conservative [21].…”

“…Regarding the significant contribution of the elastic redistribution in continuous RC beams with steel reinforcement [2], it is expected that continuous beams with FRP reinforcement give certain ability to redistribute the internal force. Redistribution of internal forces is expected as the result of cracks development and adopted reinforcement within them [1,3]. In other words, one of the basic characteristics of ductility is considered, i.e., variation of stiffness without loss of capacity of the section [4].…”

“…Certain experimental and theoretical research studies were also carried out on continuous beams with FRP reinforcement [1,3,4,[14][15][16][17][18][19][20][21][22], but not as much as they were carried out on simple beams. Mostofinejad [4] carried out research studies on two continuous beams with steel reinforcement and eight underreinforced and overreinforced continuous beams with CFRP reinforcement.…”

“…After a literature review, it is concluded that, in very few number of experimental research studies on continuous beams with longitudinal FRP reinforcement, FRP reinforcement for stirrups was used [3,14,22]. In the research studies carried out on the beams with FRP reinforcement, steel reinforcement for stirrups was mainly used.…”

Continuous beams are often used within RC structures, which are exposed to aggressive environmental impact. The use of the fiber-reinforced polymer (FRP) reinforcement in these objects and environments has a big significance, taking into account tendency of steel reinforcement to corrode. The main aim of these research studies is to estimate ability of continuous beams with glass FRP (GFRP) reinforcement to redistribute internal forces, as a certain way of ductility and desirable behaviour of RC structures. This paper gives the results of experimental research of seven continuous beams, over two spans of 1850 mm length, cross-section of 150 × 250 mm, that are imposed to concentrated forces in the middle of spans until failure. Six beams were reinforced with different longitudinal GFRP and same transverse GFRP reinforcements, and one steel-reinforced beam was adopted as a control beam. The main varied parameters represent the type of GFRP reinforcement and ratio of longitudinal reinforcement at the midspan and at the middle support, i.e., design moment redistribution. The results of the research have shown that moment redistribution in continuous beams of GFRP reinforcement is possible, without decreasing the load-carrying capacity, compared to elastic analysis. The test results have also been compared to current code provisions, and they have shown that the American Concrete Institute (ACI) 440.1R-15 well predicted the failure load for continuous beams with GFRP reinforcement. On the contrary, current design codes underestimate deflection of continuous beams with GFRP reinforcement, especially for higher load levels. Consequently, a modified model for calculation of deflection is proposed.
