Study on Flexural Performance of Damage RC Beams Strengthened with near Surface Mounted FRP Strips

Abstract

The contrast tests of 1 reinforced concrete(RC) beams and 4 RC beams strengthened with near-surface mounted carbon fiber reinforced polymer (FRP) strips have been carried out, under conditions of different damage degree of RC beams. It is mainly conducted to investigate the effects of FRP strips reinforcement of flexural strength. The experimental results indicate that significant strength on the ultimate load and rigidity of reinforced concrete beams can be realized by mounting FRP strips to the beams, and propagation of cracks were reduced obviously.

Experimental Study and Numerical Analysis of CFRP Reinforced Beam Bending Performance

“…At present, domestic and foreign scholars on the NSM method have been carrying out pilot studies and analysis of approximation theory, but less relevant research literature and engineering applications [4][5][6][7][8]. I monotonic loading test [9] for a comparison beam and four embedded reinforcement beam, the combination of Abaqus finite element software for numerical simulation analysis, the diagram of concrete, reinforced with FRP bars with load changes, and the results were compared to prove the feasibility and applicability of the Abaqus finite element. Recently Wu et al [10] proposed an analytical solution for the bond strength of externally bonded FRP-concrete joints.…”
