One of the present authors has been studied numerically the interaction curves taking account of the bucklbending (bending under the beam-column effect) on the plastic collapse and the buckling collapse by M. Kuranishi in the case of the unbraced multi-story frames with the initial plastic hinges to be formed at the base of columns. On the other side, the buckling behavior of unbraced frames resach has been so developed that plastic design metohd was prepared as the lecture note at the Lehigh Univ. and others. The most of them were presented as the approximate design methods without buckling collapse that presumed ultimate load by the iterative procedure or compatibility analysis etc. However, in this paper, present authors proposed the systematical analysis method under the assumption to given virtical loads and fixed critical sections at a given place of yield hing in order to treated the ultimate lateral loads in cluding the buckling collapse as a whole of frames. Then, the main paints of our procedure were much the same as the compatibility analysis to expected that newly considered the criterion called the Feimberg's Stability Condition. Finally, the unbraced 1 bey 2 story frames were innestigated as numerical examples.
