Probabilistic Seismic Capacity Models for RC Bridge Columns

Abstract:

Reinforced concrete (RC) columns are the vital members in bridge under the action of earthquake. In this paper, a modified Park-Ang damage model with nonlinear combination of the deformation and the hysteretic energy is proposed as a measure of RC bridge columns damage. The nonlinear combination coefficient of the modified model has been calculated based on the 151 cyclic test results of flexure dominant reinforced concrete columns. In additional, the correlation between performance levels and the values of damage index is presented. It is suggested that the scatter of the modified model at different performance levels is significantly reduced compared to the original Park-Ang damage model. At last, the probabilistic capacity models for RC bridge columns are applied to perform a damage analysis.
