Project Details

Project Description: 

Resilience is now expected by the traveling public as an integral component of any design strategy. Life-safety is also expected to ensure rapid recovery and minimal impact on the socioeconomic fabric of modern society. This realization has led to the concept of performance-based seismic design, which is a relatively new development in the design and construction of transportation infrastructure. This research is to study the seismic resilience of highway systems with a view to improving the performance of transportation systems subject to major earthquakes. Under this project, a comprehensive assessment tool to measure highway resilience shall be developed by improving current loss estimation technologies, such as the Risks from Earthquake Damage to Roadway System; factors affecting system resilience will be identified, such as damage-tolerant bridge structures and network redundancy; design aids for curved bridges and those structures in near-fault regions will be developed; and new technologies will be developed for improving the seismic performance of bridges.


The objective of this project is to study bridge seismic resilience and develop the necessary technology to improve the seismic safety of the highway system.
