Abstract: This paper presents an experimental study on twelve reinforced concrete (RC) slabs strengthened with carbon, glass, basalt fiber reinforce polymer (CFRP) laminate/sheet under four-point bending, aiming to reveal the effects of the bond-dependent coefficient, (Km) on the load-carrying capacity of strengthened the slabs at debonding failure (i.e. debonding strength). For the purpose, the test specimens are such designed to explore effects of several important factors, including modulus of elasticity of the fibers, the thickness of the used fibers, and the number of layers. The experimental results showed that the number of plies and thickness of the carbon laminate/sheet are strongly influences the debonding strengths of the strengthened slabs. It was also found that the (Afiber /Asteel) ratio is major parameter that affects the performance of strengthened slabs.
