Abstract

The objective of this study is to numerically investigate the strengthening and adhesive interface of a RC beam under shear forces. The study is based on experimental results from the current literature. The strengthening system consisted of carbon fiber reinforced polymers (CFRP) bonded in a U-shape in the critical shear regions. The numerical simulation results were considered efficient. Small differences in ductility were observed between the simulated and experimental beams, which was attributed to the failure to account for the slip of the reinforcing bars. Even with strengthening, fragile collapses are still observed, resulting from the debonding of a portion of the CFRP.
