Abstract
The use of Fiber Reinforced Polymers (FRP) as internal concrete reinforcement has gained a lot of interest worldwide and rapidly increased during the past few years because of the several of very good physical and mechanical characteristics. Knowing how concrete beams reinforced with deformed GFRP bars with normal strength concrete behaves in would add to the body of knowledge already in existence and be crucial to the continued use of deformed GFRP bars as internal reinforcement for concrete structures. An experimental study was conducted to study the flexural behavior and design of concrete beams reinforced with glass fiber reinforced polymer rebars. Twelve beams measuring 2000 mm in clear span, 120 mm in cross sectional area width and 300 mm in height, were tested under four-point loading system till they failed in the reinforced
concrete laboratory (Prof. Monir Hussein), Faculty of Engineering, Menoufia University, Egypt. Two groups were created from these twelve beams. group A consists of six beams having a concrete characteristic strength of 25 MPa. group B consists of six beams with a concrete characteristic strength of 35 MPa. Two reinforcement types were used: high tensile steel and GFRP rebars. Two different bar sizes were used (8mm and 10 mm) with reinforcement ratios 0.5% and 1%. Three-dimensional nonlinear finite elements were used to analyze the beams in order to simulate various test specimens. Numerical study was performed with the following parameters: concrete strength, diameter of the reinforcing GFRP bars, reinforcement ratio, and type of reinforcement. Results from the experiment and numerical calculations are shown, compared, and discussed. The proposed models in the analysis gave good results that agree with the experimental test results.
