| Abstract: | According to the bound failure condition of the circular cross section, the limit value of axial compressive stress ratio for concrete circular frame columns is analyzed considering factors of longitudinal reinforcement, stirrups and span to depth ratio, etc.. Based on 6 R.C model frame columns tested in laboratory, some suggestions on the limit values of axial compressive stress ratio for circular frame columns are recommended. |
