Strengthening of reinforced concrete beam can be developed by using steel plate or carbon fiber reinforced plate (CFRP) on the tension concrete fiber as an external reinforcement.
Flexural strengthening of reinforced concrete beams or slabs
The experimental evidence showed that UHPC could be used to increase the flexural strength of RC beams or slabs. Also, a cost analysis comparing with other strengthening techniques (such as CFRP) was presented. Finally, some future work is recommended to complement this promising strengthening technique for existing RC structures under flexure.

STRENGTHENING OF REINFORCED CONCRETE BEAMS USING FIBER
carbon fibre fabric strips are used to strengthen the reinforced concrete beams in shear. The experimental study consists of two control beams and eight strengthened RC beams. The reinforced concrete beams are strengthened with carbon fiber fabric vertical strips and 45° inclined strips in the form of U-wrap or in the form of a ring.

Strengthening Techniques of Reinforced Concrete Beams
Strengthening of reinforced concrete beam utilizing FRP has been applied to tackle problems related to the civil infrastructure. There are various studies which demonstrate the effectiveness of different strength techniques using FRP and considerably increase both strength and stiffness of concrete element.
Shear strengthening of reinforced concrete beams with CFRP
shear strength of continuous reinforced concrete (RC) beams. A total of seven, two-span concrete continuous beams with rectangular cross-sections were tested. The control beam was not strengthened, and the remaining six were strengthened with different arrangements of CFRP sheets. The experimental results show that the shear strength of
Strengthening of reinforced concrete beams by using fiber
These materials possess high strength capacity and corrosion resistance and can be employed as the main reinforcements in combination with adhesives and anchorages to strengthen reinforced concrete (RC) beam members. RC beams are designed to provide resistance against flexure, shear, torsion, fatigue, impact, and blast loading.
Design of steel fiber reinforced concrete beams for shear using
He found that the mean ratio and COV of experimental‐to‐predicted shear strength of SFRC beams (calculated using Level II model and VEM) were 1.07 and 0.16, respectively, which correlates well with that of Level II model for reinforced concrete beams without steel fibers.
reinforced concrete beams Related Abstracts
Four shear strength models that account for the size effect in shear are selected from the literature and applied on the datasets of slender reinforced concrete beams. Beams prepared with conventional concrete, self-compacting concrete, and recycled aggregate concrete are considered for the analysis.
