Abstract: After Hyogoken-Nanbu Earthquake in 1995,many studies about seismic resistance of steel bridge piers have been conducted. However,the most of those studies are only for new steel bridge piers or existing steel bridge piers which have not experienced earthquakes. Although small darnages caused by earthquakes are allowed of the current design code,no method exist for repairing the darnaged steel bridge pier. In this study,we propose three types of repair methods for steel bridge piers which have local damage by earthquake. We prepared sixteen circular steel bridge pier specimens which have local buckling in the bottom of pier by previous cyclic loading experiments. Afterr,repairing them, perform cyclic loading experiments under the same load sequence as previous experiments,and evaluate seismic resistance performance of the repaired steel bridge pier.
