Research Start Date:
September 1994
Expected Completion Date:
January 1996
Research Objectives:
The objective of this project was to investigate bridge damage characteristics and the impact of bridge damage on the post-earthquake performance of the transportation system in the Los Angeles area. The bridge damage assessment concentrated on correlation of damage data with ground-motion characteristics and comparison with expected bridge damage and functionality from scenario earthquake simulations. The evaluation of the performance of the transportation system focused on emergency response planning and management activities with the objectives to identify critical links within the system that are particularly vulnerable and should be considered as high priority in retrofit decisions, and to determine the optimal alternate routes when critical routes become unavailable following an earthquake.
Expected Products or Deliverables:
Databases compiled for the greater Los Angeles area. The set of compiled databases include ground motion, a description of local and state bridges, and bridge damage.
