In the present paper, a simple model to determine the moment-axial force domain of the cross-section of reinforced concrete (R.C.) columns subjected to corrosion process is presented. The model considers members with square and rectangular cross-sections and it accounts for—cover spalling; buckling of longitudinal reinforcing bars; loss of bond of bar in tension; reduction of confinement pressures (due to the reduction of the area of stirrups and cracking of concrete induced by rust formation). The analytical expressions for prediction of the area reduction of steel, bond strength and critical load of longitudinal bars utilized were verified against experimental data available in the literature. Ample verification of the analytical model proposed for prediction of moment-axial force domain was made against available experimental data given in the literature, showing good agreement. Finally, the proposed model gives simple expressions for a preliminary static check on existing cross-sections of R.C. columns subjected to corrosion processes.
