In this paper, a mechanical model for the macroscopic shear failure of both reinforced concrete membrane elements and reinforced concrete/fiber concrete deep beams in terms of entire load-displacement characteristics is developed. The analysis employs a smeared crack band model under remote shear force in a simple manner. The proposed formulation identifies a development of multiple diagonal cracks along the macroscopic shear failure plane. The model is in good agreement with a membrane elements shear test and a deep beam shear test. The procedures developed in this study would be useful in predicting the deformation behavior of reinforced concrete structures which is becoming increasingly important.
