This research shows the result of deformability evaluation of confinement design equation of ACI 318-11, ACI 318-14, CSA 3004 and NZS 2006. The database of experimental result of 163 rectangular reinforced concrete columns and moment curvature analysis were used to evaluate these confinement requirements. The result of evaluation show that CSA 2004 provide most conservative result for confinement design. The additional confinement design equations at ACI 318-13 has been improve confinement design of ACI Code. The numerical analysis showed that the provide amount of transverse reinforcement at high axial compression from each code can provide higher nominal moment but still less ductile than column subjected to low axial compression.
