A　structural　progressive　collapse　is　usually　a　local　failure,　in　which　the　damage　is　concentrated　at　beams　that　bridge　the　removal　column　and　the　column　itself.　In　many　cases,　retrofitting　the　damaged　structure　is　more　economical　and　more　sustainable　than　reconstructing　the　entire　structure.　A　progressive　collapse　test　of　a　1/3　scale,　four-bay　by　two-story　reinforced　concrete　(RC)　frame　was　conducted,　after　which　the　structure　was　retrofitted　with　carbon　fiber　reinforced　polymer　(CFRP)　wraps　and　retested.　The　center　column　in　the　first　story　was　removed　and　the　frame　was　pushed　down　quasistatically　under　displacement　control　to　investigate　the　progressive　collapse　performances　of　the　retrofitted　RC　frame.　The　test　results　were　represented　systematically　at　different　areas　in　terms　of　the　resistance　forces,　crack　developments,　and　local　and　global　failure　modes.　Numerical　models　were　built　to　verify　the　test　frame　before　and　after　the　retrofitting.　A　design　method　was　proposed　to　retrofit　an　RC　frame　using　CFRP　wraps　after　a　progressive　collapse.　The　test　frame　was　redesigned　to　improve　the　retrofitting　and　used　as　an　example　to　demonstrate　the　rationality　of　the　proposed　retrofit　design　method.　The　results　indicated　that　the　proposed　retrofitting　technology　rapidly　restored　the　frame　structure　to　its　original　capacity　before　the　progressive　collapse　occurred,　whilst　consistently　satisfying　the　priorities　of　being　economical　and　sustainable.
