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 γ_u, γ_c and γ_r. These damage factors illustrate the damage caused by increasing lateral displacements. The theoretical model has been validated against existing experimental data with good agreement.
