This paper deals with the improvement of program that was developed to analyze elasto-plastic behavior of steel square tube columns with local buckling. The improvements are the suggestion of new deteriorating hysterical rule and step by step update of plastic stiffness which can consider the effect of axial force ratio and the direction of member-end-rotation. The operation of program has been checked by the analytical examples of single column member and three dimensional building frame.
