Abstract
Reinforced concrete columns subjected to shear and high axial forces typically fail due to the crush of concrete after flexural yielding. In this paper, the design equations for the deformation capacity of these columns, which have been proposed in the authors' previous papers, are examined using the experimental data with a very wide range of structural parameters. It is concluded that the design equations give a lower boundary of experimental data, and that they are useful to predict the deformation capacity of the columns subjected to a varying axial force as well as a constant axial force.
