Rapid Post-Earthquake Displacement-Based Assessment Methodology for Bridges Phase I

This project aims to develop a rapid seismic bridge assessment method that can be used for planning (via scenarios), and for post-earthquake assessment (inspection prioritization). Unlike existing methods which are largely probabilistic, and focused on high level assessment, the proposed methodology is sufficiently versatile that it can provide a range of information, spanning from deterministic bridge specific performance, to probabilistic assessments of bridge vulnerability. With more detailed information, the uncertainty in the resulting outcome is expected to be reduced significantly. Tasks for this project will include a literature review, evaluation of limit state parameters, seismic hazard characterization for rapid assessment in Alaska, implementation plan for Phase 2, and a final report and recommendations.
