Improper execution of
bonding of FRP plates to the RC beam can result into appearance of zones where
the bond is substantially weaker, and air pockets are present. This paper
presents an attempt to model the weak bond zone and its influence on the global
response of the externally CFRP strengthened RC beam. A numerical
displacement-based fibber model was used for the prediction of the response of
RC beams externally strengthened with CFRP. Also, using the concepts of
artificial neural networks and the results of the performed numerical analyses,
another prediction model has been made. Both models generated excellent results
and some of them will be presented further below in this paper.
