| Abstract: | The paper studies the hysteretic inelastic characters of 10 large-scale RC railway pier models with low steel ratios. Destructive reasons of the models are analyzed. The ductility ratio, maximum force-resistance and embracing curve are calculated. The relationship of the shear span ratio and confinement ratio with the ductility ratio, maximum force-resistance and embracing curve are analyzed. Basic parameters for aseismic design of RC bridge piers with low steel ratios are obtained. |

| Keywords: | low steel ratio pier ductile seismic quasi-static test |
