Abstract

Abstract

In order to study the shear stress distribution law of adhesive layer and determine the debonding failure on CFRP (carbon fibre reinforced plastic) and concrete interface in concrete strengthened structure with CFRP, a tensile test with CFRP reinforced concrete specimen was maked out, and a calculation model of arbitrary point interfacial shear stress and strain was put forward based on elasticity theory.Computation result indicates that the computation result of stresses is coincidence with the test result, the model is feasible; the computation value of interfacial ultimate shear strength is 3.96 MPa, so the shear stress should be less than the value in order to prevent the debonding failure.
