Abstract EN
Concrete beams were strengthened by wrapping the shear edges of the beams twice at 45° in opposite directions by either carbon fiber reinforced polymer (CFRP) or glass fiber reinforced polymer (GFRP).
The study included 3 CFRP wrapped beams, 3 GFRP wrapped beams, and 3 control beams, all of which were 150 × 250 × 2200 mm and manufactured with C20 concrete and S420a structural steel at the Gazi University Technical Education Faculty labs, Turkey.
Samples in molds were cured by watering in the open air for 21 days.
Four-point bending tests were made on the beam test specimens and the data were collected.
Data were evaluated in terms of load displacement, bearing strength, ductility, and energy consumption.
In the CFRP and GFRP reinforced beams, compared to controls, 38% and 42%, respectively, strength increase was observed.
In all beams, failure-flexural stress occurred in the center as expected.
Most cracking was observed in the flexural region 4.
A comparison of CFRP and GFRP materials reveals that GFRP enforced parts absorb more energy.
Both materials yielded successful results.
Thicker epoxy application in both CFRP and GFRP beams was considered to be effective in preventing break-ups.
