Flexural strengthening of concrete beams with CFRP Rhino

Strengthening of Lightweight Reinforced Concrete Beams

Two of the beams strengthened with CFRP sheet at tension face on the bottom and CFRP sheet as U-wrap at the ends to increase the anchorage to the concrete. The theoretical value for the strengthened beam was calculated according to ACI 440 and compared to the experimental value from the test.

Strengthening reinforced concrete structures with FRP

The system included externally bonded FRP reinforcement on the beam soffit and CFRP U-jackets along the span. Flexural tests showed that the system was efficient in upgrading the flexural capacity of deteriorated concrete beams, despite local corrosion levels of steel reinforcement up to 57% and unrepaired concrete cover with up to 2 mm wide

The Influence of CFRP Anchorage on Achieving Sectional

3.2.2. T-Beam with Flexural CFRP Only (T2) The next beam tested is the T-beam specimen with five layers of flexural CFRP reinforcement on the bottom surface of the beam in the longitudinal direction. For the test to be considered a success, the beam had to fail at a load higher than that of the control beam. Using the Teng et al. [10] model of

Flexural Behavior of Double-Skin Steel Tube Beams Filled

The concrete-filled double skin steel tube (CFDST) is a more viable option compared to a concrete-filled steel tube (CFST) due to consisting a hollow section, while degradation is enhanced simply by using carbon fiber-reinforced polymer (CFRP). Hence, the stabilization of a concrete's ductile strength needs high- performance fiber-reinforced

Calculation on Bending Stiffness of RC Short Beam

Based on the bending tests of seven reinforced concrete (RC) short beams strengthened with carbon fiber reinforced polymer (CFRP), the bending stiffness curves of the whole process of the short beams strengthened with CFRP were obtained. The variation law of bending stiffness curve of short beam in the whole loading process was analyzed. Based on the reasonable calculation assumption,

PDF Bond Mechanism of NSM FRP Bars for Flexural Strengthening

The average compressive strength of concrete after 28 days was 48 MPa. Each beam was strengthened using one 9.525 mm diameter CFRP bar inserted into a groove cut at the bottom surface of the beam. A special concrete saw was used to cut the grooves at the bottom surface of the beam. The groove dimensions were 18 mm wide by 30 mm deep.

Parametric Study of Flexural Strengthening of Concrete

The strengthening method of using hybrid fiber reinforced polymer is an effective way to increase the strengthening efficiency and lower the cost. This paper focuses on simulating the flexural behavior of reinforced concrete beam strengthened by prestressed

Finite element analysis into the flexural response of CFRP

Strengthening of existing concrete bridges with conventional construction materials results in an increase in the dead load, and possible decrease in bridge clearance. The use of CFRP composites is considered a practical alternative for flexural strengthening of prestressed concrete bridge girders.

Flexural Strengthening of RC Beams with Prestressed CFRP

The CFRP prestressed beams exhibited a more than 50% higher carrying capacity than that of the reference beam without strengthening. They also proved to have lower deflections as well as a lower number of cracks. As a result of the research, an effective strengthening system was developed and examined in the laboratory.

Flexural Performance of RC Beams Strengthened by Carbon

The five (5) beam specimens (1 plain concrete beam, 1 control RC beam-B1, 1 pre-loaded CFRP-B2 wrapped RC beam-B3, and 2 CFRP wrapped RC beams-B4 and B5) of dimensions of 100 mm × 200 mm × 1520 mm were reinforced with two 12.7 mm diameter bars as main reinforcements, two 9.5 mm diameter two-legged stirrups spaced at 150 mm with a clear
