Flexural Behavior of GFRP RC Beam Strengthened with Carbon Fiber Reinforced Polymer (CFRP) Plate: Cracking Behavior

摘要

There has been much research conducted on the current performance of fibre Reinforced Polymer (FRP) as reinforcement. It was due to FRP easier to maintain than steel during construction because of less weight. Laboratory works on the flexural behaviour of concrete beams that with GFRP and CFRP use as a plate strengthening for the beam size 2800 × 200 × 250 millimetre. Study of the pattern of cracking and failure modes of the beam will be compared between the ten types of beams consisting of steel reinforced beams, beam-reinforced GFRP and GFRP reinforced beams strengthened with CFRP with different lengths. Comparing between the beams bending performance was examined through the ultimate load, cracking and failure modes.
