“…e control beams failed in shears, whereas the strengthened beam ductility failed, with most cracks protruding in a flexural length, indicating the successful shift of the failure mode from scissors to flexures by the integrated steel bars. In addition, the reinforced beam (Beam-B) has increased its strength by around 31% as compared to the beam control (Beam-A) [10].…”

An ecofriendly fiber reinforced polymer (FRP) had been used in the last decade to enhance the short concrete column’s strength and deformation capacity. This study involves the wrapping of FRP sheets with a thickness of 3 mm and 5 mm on a short column, and then the compressive strength is determined. The rectangular columns of size 150 mm × 300 mm are used for this study, and cast under the grades of M20 and M40 are wrapped with GFRP sheets at the thickness of 3 mm and 5 mm. These results are clarified at a specific thickness of the FRP-wrapped columns. It provides a maximum axial compressive strength, and Young’s modulus gets enhanced rigorously when it is to be compared to the normal concrete. This thesis deals with experimental studies of different parameters associated with wrapped glass fiber reinforced polymer (GFRP). In M20 grade, when the 3 mm wrapped specimen and the 5 mm wrapped specimen are compared, the specimen wrapped with 5 mm increases 5.182% more than the specimen wrapped with 3 mm. In M40 grade, when the 0 mm, 3 mm, and 5 mm wrapped specimens are compared, the specimen wrapped with 5 mm increases 2.47% more than the specimen wrapped with 0 mm. The 5 mm wrapping attains the maximum strength.

“…The solution to overcome the problem of the shear capacity of reinforced concrete beams is found in several methods, such as Externally Bonded (EB) and Near-Surface Mounted (NSM), which have been widely used to increase the shear capacity of reinforced concrete beams. Externally Bonded (EB) and Near-Surface Mounted (NSM) reinforcement systems have been shown to provide significantly increased shear capacity in reinforced concrete structures [2]. Reinforcement with EB and NSM methods requires complicated preparation.…”

The load capacity of old reinforced concrete structures must be increased to meet current standards. This might be due to increased load needs, inadequate shear provisions in the original design, material degradation, or rising demands for shear capacity related to flexural strengthening. This research demonstrates a method that effectively repairs RC beams using embedded steel bars. Loading history was reproduced in the form of cracking within the elastic range in 2000 x 150 x 200 mm beam. The beam was repaired and then reloaded to failure in the experimental test. The results show that the contribution of steel bars embedded in the core of the RC beam to the load capacity can be significant. The highest initial stiffness of the strengthened beam was 13,07 kN/mm, which was 69% higher than the control beam, while the maximum load of the strengthened beam was 43 kN with the deflection at 13,00 mm, 43% higher than the control beam. The cracks developed during the reinforced beam’s second load phase were identical to the first, and the shear capacity increased more than the control beam.
