Abstract：
Based on the seismic performance of reinforced concrete column test, in-depth study the hysteresis characteristics associated with reinforced concrete bearing capacity, stiffness degradation, strength attenuation characteristics and energy dissipation capacity. From the results of the study found that shear span ratio, axial compression ratio, stirrup ratio volume has a great influence on the bearing capacity of the three index. Under repeated load, the reinforced concrete main performance for bending shear baroclinic destruction, destruction of the two failure pattern. Axial compression ratio, it may improve the energy requirements of reinforced concrete under the action of earthquake and ductility. Finally, recommended shear baroclinic destruction, respectively in bending the corresponding formula for calculating the ultimate bearing capacity.
