چکیده
This study aims to strengthen reinforced concrete (RC) beams having insufficient shear capacity using Carbon Fibre Reinforced Polymer (CFRP) members and innovative anchorages. An method is also proposed for strengthening in interaction site of adjacent structures. Test results show that the behaviour has been improved with CFRP elements. The nonlinear finite element (FE) method, as well American Italian guidelines, are used estimate theoretical beams. compared results. It can be concluded methods reliably, design RC strengthened these performed by engineers based on simple calculations.

متن کاملInvestigation on Flexural Performance of RC Beams Flexurally Strengthened by Side-bonded CFRP Laminates
It is an effective way to improve the flexural behavior of reinforced concrete (RC) members by externally bonded carbon fiber reinforcement polymer (CFRP) laminates on the soffit of the members. However, there is little investigation on flexural performance of RC beam flexurally strengthened by side-bonded FRP laminates. To investigate the flexural behavior of RC beams side-bonded CFRP laminate...
