چکیده:

Externally bonded of FRP laminates for strengthening and increasing flexural capacity of concrete beams have been extensively common. The possibility of laminate debonding should investigate for determining the ultimate capacity of these beams. This article includes two parts. In the first part the phenomenon of premature fractures and details of debonding of laminate/concrete are explained and relevant theoretical model are introduced. In the second part, with using empirical results that obtained by researchers, accuracy of presented model by researcher that is able to predict of failure load at the time of premature fracture is investigated
