A deformation capacity is formulated in this paper for seismic design of reinforced concrete columns. It is determined by two criteria. One is the stable limit which was defined in the authors' previous paper. The other is a particular deformation point with a cyclic deterioration in lateral load-carrying capacity and a development of axial shortening in columns under cyclic loadings, discussed here in detail. With the formulas, the effects of the axial stress level at the section and the characteristics of the stress-strain curve of concrete on deformation capacity of columns are able to be evaluated.
