Symmetry limit has been defined for cantilever beam-columns subjected to completely reversed cyclic tip deflection program with continuously increasing amplitude, named COIDA, under constant compressive axial load and the symmetry limit theory has been established for predicting it. It may be inferred from the limit theory that symmetry limit would also exist in beam-columns subjected to a completely reversed cyclic tip lateral force program with continuously increasing amplitude, named COIFA. In the present paper, the symmetry limit theory for the COIDA problem will be extended to the COIFA problem. It will be verified by numerical analysis of the hysteretic behavior of beam-columns that the symmetry limit of beam-columns subjected to COIFA program actually exists and can exactly be predicted by the extended symmetry limit theory.
