The bridge columns with lap-splice reinforcements in earthquake suffered a brittle bond-slip failure due to deterioration of the lap-spliced longitudinal reinforcements. In this case, such a damaged bridge pier can be repaired using FRP wrapping. The damaged column using FRP wrapping showed better improvement than existing one in seismic performance due to FRP's confinement effect. This paper presents the experimental study of damaged circular bridge pier repaired with FRP wrapping for poor lap-splice details.
