【Abstract】 Eight reinforced concrete columns with central reinforcement (RRC column) were tested under high axial compressive ratio and cyclic lateral loading. Seismic behavior of RRC columns and their influencecial factors were studied. The test results show that RRC columns have excellent ductility and energy dissipation capacity. Seismic behavior of concrete columns under high axial compression ratio can be improved effectively by the central reinforcement. The main factors that influence the seismic behavior of RRC columns are the percentage of central reinforcement, equivalent ratio of axial compression and characteristic value of stirrups. By analysis of the test results, it is recommended to increase the limit value of the axial compression ratio of RC columns by central reinforcements. Besides, the design requirements of RRC columns are also suggested in the paper.更多还原
