Debonding Failure Analysis of Reinforced Concrete Beams Strengthened with CFRP Plates

In this study, experimental work was carried out on reinforced concrete (RC) beams strengthened with carbon fiber polymers (CFRP) plates. This study aims to examine the effect of reinforcement ratio flexural behavior these and propose a new model for predicting debonding moment. Six RC consisting three control CFRP plates were tested. The simply supported loaded four-point bending. test variable tensile (1%, 1.5%, 2.5%). Analytical prediction using element method also obtain complete theoretical response beam due loads. results show that affected bending performance Following this, data from 60 published literature analyzed. From data, it found reinforcement, modulus elasticity concrete, plate, plate thickness all affect value A parametric elements two-dimensional finite confirm variables failure. These then used develop an equation predict moment plates, simple statistical analysis. analysis resulted in Then is entered into computer program, cross-section failure can be obtained.
