Steel rebar buckling is an important failure mode in reinforced concrete (RC) columns. Fiber-reinforced polymer (FRP) composites provide an effective mean that can restrain or delay longitudinal rebar buckling. To accurately predict the strength and ductility of FRP-strengthened rectangular RC colum...
