| Abstract: | Through test and analysis on the bonding specimens of young on old concrete, the mechanics model is given. The model can calculate the restrained force on the bonding interface and the stresses distribution on the transverse section. The force and stress increase as the time grows, and reach the maximum values when the shrinkage of the new concrete finishes. The distribution of strains on the section of the bonding specimen conforms the hyperbolic shape. |
