Steel column testing in which a compressive axial force and a cyclic biaxial bending moment were applied simultaneously was conducted in order to clarify the structural performance of the column. Although the AIJ beam‐column design formula provided overly conservative results, the correlation equation for full plasticity evaluated the results with reasonable accuracy. The loading direction was not crucial to the plastic deformation capacity. As a result, the limitation applied to columns in order to guarantee sufficient plastic deformation under a loading direction of 0‐degree can also be used for columns with a loading direction of 45‐degree.
