摘要
Abstract
Based on the test results, the failure mechanism of the adhesive layer of young on old concrete is presented. Under the Mises yield condition and Coulomb shear failure condition, the theoretical solution for shear strength of adhesive layer of young on old concrete is deduced, and the factors, which affect the shear strength of adhesive layer, are also determined with the upper bound theorem of plastic limit analysis. The effect of each factor has been analyzed deeply with the failure mechanism, and it is pointed out that the proper roughness of the adhesive surface of old concrete is beneficial to obtain higher shear strength.
