David Yang, an assistant professor in the Department of Civil and Environmental Engineering at Portland State University, is the principal investigator on two newly-awarded research projects for the Federal Highway Administration (FHWA) in support of its structural engineering programs.
"As the transportation infrastructure continues to age in an ever more uncertain future, it is essential to assess and manage infrastructure risk during the evaluation, maintenance, and rehabilitation processes. These two projects are dedicated to the development of such risk-informed approaches for existing culverts, bridges, and tunnels," Yang said.
In the first project, Framework and Methodology for Risk-Based Bridge and Tunnel Asset Management, an infrastructure team led by Yang with co-PIs Diane Moug, Arash Khosravifar, and Avinash Unnikrishnan will use a three-year grant from the Federal Highway Administration to develop a framework and a methodology for asset management of bridges and tunnels.
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...Read more
