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 in earthquake. In this study, the repairing effect of filling concrete for circular steel bridge piers which have different degrees of damage is to be verified. First, four damage levels were assumed from general load-deflection relationship of the steel bridge pier. Static cyclic loading tests until reaching their predetermined 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. Then, the seismic performance has been evaluated by the load-deflection relationship and the strain value during cyclic loading. |
