Abstract

This paper presents an evaluation method for shear capacity of RC members retrofitted with externally-bonded Continuous Fiber (CF) sheets. The proposed method is on the basis of coupled mechanical models. Opening of diagonal shear crack is calculated by the simplified rigid rotational model. Bonding and debonding behavior of CF sheet is calculated by the constitutive model for the interface between CF sheet and concrete. Since it is based on the realistic mechanical assumptions, the method can automatically distinguish the failure mode of members, which are “compression shear failure” and “rupture of CF sheet”.<br>The accuracy and applicability of the proposed method were verified through analysis of number of experimental data in the literature. It was proved that the proposed method can predict shear capacity of members with higher accuracy than the equation used in the current design.
