The elasic-plastic behavior of the working stress designed full-scale gable frame against symmetrically vertical load was observed, and was examined using the theories of Part (I) and Part (II) in this study. In this test, the gable frame showed the asymmetrical by swayed elastic-plastic buckling mode before symmetrical failure without showing a local or lateral buckling. This failure load could not be predicted by the theory that we reported in Part (I), for the value of W_<cr>/W_e was below the transition line. This failure mode was, however, well predicted by the theory of Part (II) in which we considered the deteriorated effect of yielding regions, and the critical value of W_<cr>/W_e of this frame was plotted within expanded the transition area in Part (II).
