چکیده:

In this paper, different types of debonding failure modes are described. Then experimental results of four-point bending tests on FRPtrengthened RC beams are presented and debonding failure mechanisms of strengthened beams are investigated using analytical solutions. Existing
international codes and guidelines from organizations such as fib, ACI, ISIS, TR55, JSCE, etc. are presented and compared with the results from the experiments and calculations. A discrepancy of up to 250% was seen between different codes and guidelines for predicting the debonding load.
