SEISMIC: Utilization of Strong Motion Data for Toll Bridge Damage Assessment

This project will use strong motion data from sensors placed on toll bridges for immediate damage assessment following a large earthquake. After identifying the vulnerable components, the project will develop demand-to-capacity charts or other tools for key components of the structures. These charts will be used to compare the recorded relative deflections to the system capacity after a seismic event. Also, this project will provide a means to coordinate with the California Geological Survey (CGS) to prioritize processing and distribution of strong motion data following a major earthquake. In addition, an avenue will be created to provide the toll bridge maintenance inspection group with this information after an earthquake.
