To understand the effect of bond strength on the initial stress release and transfer efficiency of steel tube, based on the new idea of the initial stress release and transfer of steel tube, a CFST axial compression members with initial stress and a CFST arch bridge with medium bearing single round pipe as an example, the finite element method is used to analyze the stress and displacement changes of steel tube and concrete after the steel tube "cut off" under the conditions of different interfacial bond strength, then some debonding measures can be adopted in the concrete filled steel tube interface were put forward. The analysis shows that when the bond force is lower than the critical value, the release and transfer efficiency of the initial stress of the steel tube increases with the decrease of the bond force, for CFST arch bridge, the transfer efficiency near the arch feet on both sides is higher than that of the vault. When the bond strength is close to zero, the initial stress of the steel tube can be completely transferred to the core concrete, it proves that the interfacial bond strength of the concrete filled steel tube is the main factor affecting the release and transfer efficiency of the initial stress of the steel tube.
