Framework and Methodology for Risk-Based Bridge and Tunnel Asset Management

David Yang, Portland State University



Bridges and tunnels need to address the daily transportation needs of the traveling public and provide capacity and emergency service before/during/after extreme events. States may achieve the best possible transportation network performance through a properly planned asset management strategy. This project aims to develop a comprehensive and risk-based methodology that can consider all credible risks and their variations when maintenance and retrofitting actions are selected and implemented. This project will examine both regular operation, such as daily traffic fluctuation or planned maintenance/construction, and extreme events that have recurring intervals significantly greater than bridge design life span.
