SEISMIC: Calibration of Probabilistic Damage Control Approach for Seismic Design of Bridges

Probabilistic Damage Control Approach (PDCA) is a new damage index developed by Caltrans staff to assist the Owner, the Bridge Design engineer, and the Bridge Maintenance engineer in quantifying seismic damage to bridges. In PDCA, the performance levels are defined in the range of life safety state to no collapse state and in between, based on acceptable damage and hazard levels, or the probability of hazard exceedance within a certain number of years. The performance level is classified based on a null factor called damage index (DI) that will have direct correlation to the damaged state of the bridge. In this approach multiple levels of performance can be compared for a specific probabilistic hazard level or multiple probabilistic hazard levels.
