By means of shear transfer theory, the shear failure mechanisms of reinforced concrete short columns are investigated. As the basis of this study, it is assumed that the deformation of columns by shear loading is divided into three types, that is, flexural, bond failure and shear slip deformations. The ultimate state is reached when the shear loading causes shear slip along diagonal tension crack in core concrete and yield confining forces in tie reinforcing bars occur. The equations which give the ultimate shear strength of reinforced concrete short columns are derived. The analytical results show good agreement with experimental results by the authors and other researchers. It is concluded that sufficient tie reinforcement may make it possible to avoid the shear failure of columns.
