| Abstract: | New on old concrete adhesive specimen and whole specimen are done by nonlinear module in ANSYS in which large deformation and contact are simultaneously considered. The stress distribution law of adherence of new on old concrete under biaxial stresses is studied as viewed from stress analysis. The effects of strength of new concrete and compressive stress on adhesive strength are investigated. The adhesive strength behavior of new on old concrete under biaxial stresses is studied. |

| Keywords: | nonlinear contact analysis adherence of new and old concrete adhesive specimen |
