Abstract Combined with the results in the ultimate strength tests of 22 reinforced concrete of simply supported beams under bending moment, shear force, axial tensile force and the FEA results, the range of values of the shear transfer coefficients for open and close cracks and their influences on the calculation results were studied. In the study, the pre-crack of beams, the axial tensile force, the reinforcement ratio and the concrete strength grade were considered. The result reveals that the shear transfer coefficients for open and close cracks of Solid65 have large influences on the FEA results. When the shear transfer coefficients for open crack C1 = 0. 35 - 0. 40 and the shear transfer coefficients for close crack C2 = 0.9-1.0, the FEA results show good coincidence with the tests results. This conclusion can be used in FEA of reinforced concrete beams.
