Abstract: Since HYOGOKEN-NANBU Earthquake in 1995, a large number of researches on the seismic performance of steel bridge pier have been carried out. However, there is very few research for the repair method of the steel bridge pier that has been damaged by earthquake. The research on how to repair severely damaged steel bridge pier has been conducted by the authors, but the effectiveness of repair for the steel bridge pier that suffered minor damage has not been revealed. In this study, the repairing effect of filling concrete for rectangular cross sectional steel bridge piers which have different degrees of damage is to be verified. First, four damage levels were assumed from general load-deflection relationship. Static cyclic loading tests until reaching their predetennined damage levels were conducted. After filling the concrete inside the specimens, the same static cyclic loading tests were carried out to clarify the seismic performance of repaired piers.
