An analytical model for the determination of the compressive response of R.C. members having circular transverse cross-section and reinforced with traverse steel and longitudinal bars is presented. The model able to include also the contribution in confinement due to transverse and longitudinal bars was verified against experimental data recently generated by the authors and those available in the literature. Also comparison was made with the predicted values given with recent models presented in the literature. Finally, a comment on the design prescriptions given by International, European and National codes in relation with the results here obtained is made.
