Reinforced concrete (RC) beams which are insufficient in terms of shear and flexural capacities are strengthened by various methods. Steel and fibre reinforced polymer (FRP) plate bonding methods are very widely used in strengthening of beams. Strengthening methods such as bonding steel and FRP plates have deficiencies as corrosion, fire and ...
Seven concrete beams reinforced internally with steel and externally with carbon fiber-reinforced polymer (FRP) laminate applied after the concrete had cracked were tested under four-point bending. Results show that FRP is very effective for flexural strengthening.

One application of composite materials in civil engineering is examined: the strengthening of a reinforced concrete beamin situ by externally-bonded fiber reinforced plastic (FRP). Studies of the mechanical properties of the interface and the rheological behaviour of composite materials are very important to design. For the experimental determination of the mechanical properties of the ...
The strengthening of reinforced concrete members with prestressed fibre-reinforced polymer laminates has been investigated by researchers due to major improvements in member serviceability characte...
Using externally bonded (EB) carbon fiber reinforced polymer (CFRP) laminates is nowadaysa common technique to improve the flexural capacity of reinforced concrete (RC) members. The first application of bonded CFRP composites for flexural strengthening of reinforced concrete bridges took place in late 1980s (Bakis et al., 2002).

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.
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.
Jun 06, 2013 · The experiments indicated that the beam ductility increases as the plate thickness decreases, and the anchorage of the plate to the beam through bolts or collars proves to be an efficient method for preventing the premature plate peeling failure and achieving sufficient ductility in beams strengthened with thick solid plates.

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
Iron based shape memory alloys (Fe-SMA) have recently been used as active flexural strengthening material for reinforced concrete (RC) beams. Fe-SMAs are characterized by a shape memory effect (SME) which allows the recovery of previously induced plastic deformations through heating. If these deformations are restrained a recovery stress is generated by the SME. This recovery stress can be ...
