The problems of the shear strength of the reinforced concrete members have been studied by manyresearchers. However there are few studies on the shear strength of reinforced concrete beam under the axial tensileforce. In this paper the effects of the axial tension on the shear strength and the failure status of the beams areanalyzed experimentally. In experimental studies, 78 simply supported beams having rectangular cross section aretested under axial tension and bending. The parameters adopted herein are the axial tensile force levels and the shearspan lengths. Considering the insufficient definitions of the Specification for Concrete the adequate regressiveequations are defined based on the experimental results.
