| Abstract: | A new type of test rig is designed and nineteen Z shaped shear specimens are studied. The influence of the initial crack width, mean restraining stiffness and concrete strength is considered. A mean coefficient of friction on cracked surface is given. In addition, fitting formula about the relation of the shear stress and the shear displacement on the cracked surface in concrete is given. |

| Keywords: | concrete crack shear stress/shear displacement aggregate interlock behavior |
