In this study, uniaxial compressive test of ultra-high strength square CFT stub columns was carried out to clarify the effect of column size and steel contribution ratio to its structural performance. The results of experiments were analyzed to clarify differences between structural behavior of CFT stub columns and that of individual steel tubes or concrete. In addition, the applicability of the simple cumulative strength formula is verified.
