Research on Debonding Formula Model of RC Beams Strengthened with CFRP Sheets
Debonding of concrete occurs when the interface principal stress reaches the ultimate tensile strength. We propose the use of carbon fiber plate attached to the beam bottom, which makes finite element analysis of the mechanical properties of debonding concrete beams more reasonable. In addition, formulas of this theory are given and applied in the finite element analysis. Finally, it is shown by a number of experimental results.
