Abstract-Glass fiber reinforced polymers (GFRP) bars are non corrosion materials, their tensile modulus relatively are lower compared to steel reinforcement. A total of three beam specimens (GB1~GB3) were simulated under four-point bending. The main parameter's studies were the amount of GFRP reinforcement ratio, concrete strength, concrete cover thickness and the height of beam cross-section. To study the influence of these parameters on the flexural behavior of GFRPs concrete beams, ABAQUS Finite-element software was used. The results showed that; there are clear improving of bearing capacity when the reinforcement ratio and height cross-sections of the beam were increased, but increase of concrete strength lead to increases as the bearing capacity, but this increased is limited by concrete compressive failure strain of reinforced concrete beams, while increasing the concrete cover thickness, lead to a negative efficient of GFRP reinforced concrete bearing capacity.

In the 1940's, potential of glass as a construction material was realized and improvement continued with the addition of zirconium dioxide in 1960's for harsh alkali conditions. To enhance durability of materials, new generation of glass fibres directed to improvement process. In this way, glass fibre reinforced concrete (GFRC) was started to produce for the satisfaction of different demands. Scientific studies and tests on the GFRC have shown that the physical and mechanical properties of the GFRC change depending on the quality of the materials and the accuracy of the production methods. GFRC can be used wherever a light, strong, fire resistant, weather resistant, attractive, impermeable material is needed. As technology advances, it is possibly expected to build the whole building and complex freeform with low cost. In recent years, the effect of glass fibres in hybrid mixtures has been investigated for high-performance concrete (HPC), an emerging technology termed, which has become popular in the construction industry.

“…Several investigations have confirmed the availability of using steel reinforcement to improve the ductility and the energy-dissipating capacity of the members for seismic applications. For example, Kara et al [26] and Li et al [27] investigated the flexural behaviour of composite beams reinforced with FRP bars and rebars; Yu et al [28] conducted a research study on beam members reinforced with CFRP jackets and steel tubes; Hadi et al [5] tested beam specimens reinforced with the FRP I-section beams and rebars. Apart from the improvement of the ductile response, the steel reinforcement normally contributes to the higher bending stiffness of the beam members due to the higher elastic modulus than that of the FRP composites.…”

The ductile behaviour of composite beams reinforced with glass fibre-reinforced polymer (GFRP) pultruded rectangular tubes was investigated in this paper. The composite beams were reinforced with GFRP tubes and different steel products, aiming to improve their ductility by using steel products. The main parameters were the types of the steel reinforcement, namely rebars and steel angles. The flexural behaviour of four beam specimens was tested by using a four-point bending test. The experimental results show that the yield load of the specimens was determined by the steel products and the ultimate load was controlled by the GFRP tubes. Two ductility methods (displacement ductility and energy ductility) were used to evaluate the change of the ductility. Both the methods confirmed that the ductility of the composite beam was improved in varying degrees by using rebars and steel angles. Moreover, the analysis shows that improving the yield load or decreasing the ultimate load of the composite beams contributed to the improvement of the ductility.
