For SBN, SBM, SBL specimens, there were an increase in ultimate load of up to 56% and deflection of up to 63.5% compared to control beam. Debonding of the CFRP plates happened in S-EBR specimen as expected. Delamination was observed in SBN, SBM and SBL specimens which confirms that bore-epoxy anchor can eliminate the debonding in CFRP. Failure of beams strengthened with bore-epoxy is more ductile than other control ones.
