In this paper the influence of the concrete compressive strength and the reinforcement ratio on the shear transfer across cracks are studied experimentally and theoretically. Tests on 84 specimens of the push-off type are reported. Most of the specimens were precracked along the shear plane. Among other things steel strains and shear stress - displacement relationships were measured. On the basis of the tests formulas for the dowel action and aggregate interlock forces are suggested.
