Abstract:
An hypothesis of the mechanism of shear failure of reinforced concrete beams is developed from studies of the behavior of several conventional beams tested with special instrumentation, and of a number of beams especially constructed to show the contributing resistance to external shear of the longitudinal steel acting in conjunction with the embedding concrete. Some data are provided to show the effects of bar size, bar spacings, depth of cover below the bars, and concrete strength on such dowel resistance.
