Abstract: The rehabilitation of existing Reinforced Concrete (RC) structures becomes necessary due to defects in design/construction, ageing, damage due to earthquake/fire, corrosion of reinforcing steel, demand in the increased service loads and revisions in the design guidelines. Rehabilitation of RC structures can be done in various ways such as repairing, retrofitting & strengthening. Fiber Reinforced Polymers (FRP) has emerged as the promising material for rehabilitation of deficient RC structures and accepted by construction industry due to ease of application. Beams are flexural elements in RC framed structures. From the previous researchers, it is revealed that most of the work is done to study the flexural behavior of RC beam deficient in flexure by applying GFRP laminates for full length on tension face of the beam or U-wrapping. In this way, the GFRP laminates applied on shear zone cannot be efficiently utilized for flexure strengthening. In the present research work, the effect of varying length of GFRP laminate on flexural behavior of deficient RC beams was investigated. The investigation was done on beams with GFRP laminates applied on tension side and subjected to three-point static loading system. Finite Element Analysis (FEA) of the similar specimens were carried out using ANSYS. The results obtained from ANSYS were in good agreement with the experimental investigation. From the test results, it was observed that flexural capacity of RC beams varied with the length of GFRP laminate applied.
