| description | Enhancement of the response of reinforced concrete (RC) beams applying fiber-reinforced polymer (FRP) reinforcement bars has become a popular structural technique over the past two decades as a result to the well-known advantages of FRP composites including their high strength-to-weight ratio and excellent corrosion resistance. This study presents numerical investigation of 20 concrete beams internally reinforced with GFRP bars without web reinforcement. The accuracy of the non-linear finite element model in ABAQUS software is first validated against experimental data from the literature. The study presents an investigation into the behaviour of FRP reinforced concrete beams including the evaluation of geometrical properties effects. In particular, the study is focused on the effects of span/depth ratio, the reinforcement ratio and the effective depth of the beam, aiming to correct deficiencies in this area in existing knowledge. It’s been revealed that the finite element model is capable of accurately simulating the flexural behaviour of FRP reinforced beams. It was able to predict, with high accuracy, the force-displacement response the beam. Results manifested that FRP reinforcement is a proper solution in order to boost the ductility of RC beam members. Moreover, although that increasing in the span/depth ratio of the beam decreases beam’s rigidity, however; it also postpones the yielding point in the beam’s flexural response and leads to a higher level of displacement ductility for the beam. |
