CHAMPAIGN, Ill., VICKSBURG, Miss.—ERDC Construction Engineering Research Laboratory’s (CERL) Steve Sweeney, Rich Lampo, Vince Hock and Mike McInerney, and ERDC Geotechnical and Structures Laboratory’s (GSL) Vincent Chiarito and Henry Diaz-Alvarez, along with industry collaborators have been selected to receive the 2012 Fiatech Celebration of Engineering and Technology Innovation (CETI) Award for "World's First Fully Integrated Structural Health Monitoring (SHM) System for Steel Truss Bridges."
Fiatech is an international community of passionate stakeholders working together to lead global development and adoption of innovative practices and technologies to realize the highest business value throughout the life cycle of capital assets.
The CETI Award recognizes significant achievements in technology research, development, and implementation in the capital projects industry. An annual award, the CETIs recognize organizations and individuals: organizations for implementing new and emerging technologies, and individuals for making significant strides in advancing innovation in research and development.
The SHM system provides detection, monitoring, and warning of potential failure of steel bridges based on integrated engineering models and a network of sensors including strain, temperature, tilt, acceleration, acoustic emission, and corrosion.
Previous SHM systems only monitored individual bridge components rather than the entire bridge as a unit, and the complexity of steel truss bridges caused them to be difficult to model and analyze.
The new system translates the results of the analysis into a simple "red-amber-green" status display that is easy to interpret.
The system is installed on the Government Bridge at Rock Island Arsenal, Ill., as well as the I-20 Mississippi River Bridge near Vicksburg, Miss.
Fiatech will honor awardees at its Technology Conference and CETI Award Gala, March 26, in San Antonio, Texas.
