In order to evaluate the deformation capacity of a concrete filled steel tubular slender column, investigation of a previous restoring force characteristic model and a evaluating equation of deformation capacity was conducted. Firstly, the application scope of the previous model and the evaluating equation were clarified. Consequently, it was understood that the restoring force characteristic model could be applied to CFT slender columns. However, it was thought that the evaluating equation of deformation capacity was inapplicable to CFT slender columns. Then, the evaluating method of deformation capacity of CFT slender columns was proposed based on the previous restoring force characteristic model and a evaluating equation.
