Experimental Studies on the Bonding Failure between CFRP and Concrete in RC Two-Way Slabs Strengthened with CFRP Strips

Article Preview

Abstract:

It is well known that the bonding failure between concrete and externally bonded CFRP strips sets in where high shear forces and high bending moments occur. Despite this knowledge, experimental and theoretical studies had been exclusively focused on the bonding failure modes at the end of the CFRP-strip. This paper deals with strengthening of RC two-way slabs with CFRP strips bonded to the tensile face. It focuses on the bonding failure by dealing with an experimental study. The CFRP-strips strengthened slab test presents a failure mode with debonding of the external CFRP strips from the slab.
