Abstract

Self-centering concrete bridge piers (SCCP), which have been used to retrofit bridge piers to give better seismic response, effectively reduce residual displacements during severe earthquakes. This study gives a simplified theoretical model for self-centering concrete bridge piers including a stiffness deterioration analysis and lateral force-displacement analysis. The stiffness deterioration analysis introduces 3 damage factors for γu, γc and γr. These damage factors illustrate the damage caused by increasing lateral displacements. The theoretical model has been validated against existing experimental data with good agreement.
