About the research


--Develop risk assessment procedures to identify critical bridges in a bridge network --Develop bridge vulnerability assessment guide --Develop concepts for mitigation and structural protection of bridges Abstract Soon after the attacks of September 11, 2001, the Federal Highway Administration (FHWA) and the American Association of State Highway and Transportation Officials (AASHTO) assembled a Blue-Ribbon Panel of experts to develop strategies and provide guidance to improve the safety and security of bridge and tunnel infrastructure. This effort led to recognizing that the threat is real and can be devastating, risk assessment is necessary, and engineering guidance are needed based on research. Building on current and past efforts, the goal of this project is develop procedures to assist professionals and bridge owners identify critical bridges and to develop procedures to assess their vulnerability to explosions (terrorist?s bomb attacks). Potential Benefits of the Project The procedures and design guides developed in this project will benefit the bridge owners, designers, inspectors, and professionals nationwide.
