This paper is an experimental study to research the maximum strength and deformation capacity of the cold-formed square tubular members under compression. On short and long columns, yield strength, maximum strength and deformation capacity have particular relation d/t ratio and slenderness. In this study, through compression test of short and long columns concerning d/t ratio, we investigated the local buckling strength, yield strength, maximum strength and plastic deformation capacity of members.
