In CFRP bonded steel members, the shear stress is caused in the adhesive by temperature change, due to difference in coefficients of thermal expansion between steel and CFRP. CFRP strips are often separated from steel plates by the debonding shear stress, which is the high shear stress developed in the adhesive at the ends of the CFRP strips. In this research, the debonding shear stress induced by temperature change is theoretically analyzed for CFRP bonded steel plates and also for the case a glass fiber sheet is inserted under CFRP strips. The analytical results are confirmed by the measurements of the strains created by temperature change in CFRP bonded steel plates.
