Through experimental study on three HRB400 steel bar reinforced concrete columns subjected to low cyclic reversed loading, the failure patterns, hysteretic curves and skeleton curves were obtained. The influence of longitudinal high-strength reinforcement ratio upon the hysteretic characteristics, ductile behavior and ability of energy dissipation were analyzed. The results show that the main failure pattern was bending failure; and with the increscent of the longitudinal high-strength reinforcing steel bar ratio, the columns can endure larger seismic loads and displacement; the seismic performance of the whole reinforced concrete columns can be effectively improved by arranging reasonable high-strength steel bars.
