Abstract

Analytic analysis is applied for interfacial stress in cracked RC beams strengthened with CFRP, and analytic solutions to debongding stress distribution are obtained on the basis of differential equations of the interfacial stresses of composite plate. Through instance calculation, influence on debonding stress distribution by anchorage length and the same area of CFRP plate with different widthes and thicknesses are studied, shear-debonding interaction is also estimated, which may provide some theoretic guidance for design and construction for CFRP-strengthened concrete structure.
