Experimental evaluation of energy dissipation and viscous damping of repaired and strengthened RC columns with CFRP jacketing under biaxial load

•8 RC columns tested under biaxial load, repaired and retrofitted with CFRP sheets.•Efficiency of the retrofit was evaluated in terms of energy dissipation and equivalent viscous damping.•The repair strategy restored the energy dissipation capacity of the damaged columns.•The use of CFRP jacketing i...
