The idea of symmetry limit arose first from the results of cyclic forced-displacement bending test of steel beam-columns and the symmetry limit theory has been established for cantilever beam-columns subjected to completely reversed cyclic tip deflection program with continuously increasing amplitude, named COIDA. In the preceding part of this paper, the original symmetry limit theory has been extended to beam-columns subjected to completely reversed cyclic tip lateral force program with continuously increasing amplitude, named COIFA. The purpose of the present study is to prove the existence of the symmetry limit under COIFA program and clarify the characteristics of the critical behavior beyond the symmetry limit by performing completely reversed force-controlled cyclic bending test of steel beam-columns with stepwise increasing amplitude program.
