The neglect of the shear force on the longitudinal rein-forcement (dowel force) in reinforced concrete beams with-out shear reinforcement is questioned. Analysis of tests on simple rectangular beams shows that the assumption of zero dowel force implies high stresses on the concrete at the top of the diagonal crack. It is suggested that the magnitude of the dowel force and its point of action are important fac-tors in deciding the mode of shear failure of such beams.
