This paper describes ultimate behavior of beam- column which was made of a cold-rolled steel square tube under proportionally varying axial and bi-directional lateral loads. Main findings were as follows. 1) The specimens were able to be roughly classified into two groups. One included the specimens under uniaxial bending load and had been normalized or as rolled. Another included the specimens under biaxial bending load and as rolled. It was on the corner of the local buckling section where the cracks grew on the former ones and it was the toe of the weld on the latter ones. 2) The as-rolled tube subjected to axial force and biaxial bending moment showed larger deformation capacity than which under no axial force and uniaxial bending moment.
