Abstract: Since the Great Hannsin Earthquak, many researches had been performed experimental studies on the steel bridge piers. But few works had presented high performance of seismic resistance for them. In this study, new idea improving the ductility of steel bridge piers is proposed,in which steel piers have ac entral core column. Cyclic loading test is conducted to certify the seismic performance using steel tubes of steel grade SS400 and STK400 with 600mm diameter,changing the radius to thickness parameter Rt= 0.066 to 0.131 and the axial force ratio P/Py= 0.15 to 0.35.Comparing with conventional piers, the pier models with central core column show an excelldet high seismic performance.
