An　experimental　study　was　conducted　to　investigate　the　feasibility　of　a　proposed　rapid　repair　technique　for　severely　earthquake-damaged　bridge　piers　with　flexural-shear　failure　mode.　Six　circular　pier　specimens　were　first　tested　to　severe　damage　in　flexural-shear　mode　and　repaired　using　early-strength　concrete　with　high-fluidity　and　carbon　fiber　reinforced　polymers　(CFRP).　After　about　four　days,　the　repaired　specimens　were　tested　to　failure　again.　The　seismic　behavior　of　the　repaired　specimens　was　evaluated　and　compared　to　the　original　specimens.　Test　results　indicate　that　the　proposed　repair　technique　is　highly　effective.　Both　shear　strength　and　lateral　displacement　of　the　repaired　piers　increased　when　compared　to　the　original　specimens,　and　the　failure　mechanism　of　the　piers　shifted　from　flexural-shear　failure　to　ductile　flexural　failure.　Finally,　a　simple　design　model　based　on　the　Seible　formulation　for　post-earthquake　repair　design　was　compared　to　the　experimental　results.　It　is　concluded　that　the　design　equation　for　bridge　pier　strengthening　before　an　earthquake　could　be　applicable　to　seismic　repairs　after　an　earthquake　if　the　shear　strength　contribution　of　the　spiral　bars　in　the　repaired　piers　is　disregarded　and　1.5　times　more　FRP　sheets　is　provided.
