Abstract: The aim of the present review is to study the influence of aggregate interlocking across cracked surface, reinforcement crossing the shear cracks and dowel action of longitudinal tensile reinforcing bars across the cracks. The aggregate interlocking is uncertain and depends on the shear reinforcement and action of loads under the and dowel action of reinforced concrete beams under flexural loading. In reinforced concrete beams, shear resistance is provided by shear transfer in un cracked compression concrete, supports. Similarly, dowel action is an important component for shear resistance. Due to complexity involved in shear transfer mechanism, the prediction on the effect of both aggregate interlocking and dowel action is a difficult task. Previous research had given focus on both the components separately. The present review is to study the effect of both aggregate interlocking and dowel action as common entity and understand the relationship of the same.
