Debonding-Related Strain Limits for Externally Bonded FRP Sheets in Flexurally Strengthened Reinforced Concrete Beams
Debonding problems of externally bonded fiber reinforced polymer (FRP) sheets in flexurally FRP-strengthened reinforced concrete (RC) beams have been a concern and a research challenge since their application of this strengthening technique. Intermediate crack induced debonding is the most common failure mode which is that the debonding initiates at the critical flexural-shear or flexural crack...
متن کاملNumerical Simulation of Debonding Failure of Reinforced Concrete Beams Strengthened with Externally Bonded Frp
As the life age of the existing structures are required to meet the changing demands on civil infrastructures. So strengthening and retrofitting are required. Recently many techniques to strengthen the reinforced concrete beams in flexural by using fiber reinforced polymer (FRP) had appeared. The most famous technique among them is strengthening the (RC) beams with externally bonded FRP sheet t...
متن کاملEffect of Shear Resistance on Flexural Debonding Load-Carrying Capacity of RC Beams Strengthened with Externally Bonded FRP Composites
Debonding failure is the main failure mode in flexurally strengthened reinforced concrete beams by externally bonded or near surface mounted fibre reinforced polymer (FRP) composites. It is believed that FRP debonding will be initiated if the shear stress on the concrete-FRP interface reaches the tensile strength of concrete. However, it was found through experimental and analytical studies tha...

متن کاملDebonding Failures of Rc Beams Strengthened with Externally Bonded Frp Reinforcement: Behaviour and Modelling
Both the flexural and shear strengths of reinforced concrete (RC) beams can be substantially enhanced using externally bonded fibre reinforced polymer (FRP) composites. Failures of such FRP-strengthened RC beams often occur by debonding of the FRP plate from the RC beam in a number of forms. Despite numerous theoretical and experimental studies on debonding failures of FRP-strengthened RC beams...
