Abstract：Based on 3D printing technology and characterization of artificial roughness by fractal dimension,the compression-shear test of new-to-old concrete members was carried out. The influence of bonding-agent of AY/HY133LP and roughness on shear strength was studied. The test results show that under the same conditions of roughness and normal pressure,the bonding shear strength of new-to-old concrete was increased with the bonding-agent of AY/HY133LP. The simplified calculation method of shear strength of new-to-old concrete under different pressure conditions was summarized based on the test results,which can pro-vide some reference for engineering designers.
