Four steel bridges located on a remote stretch of Interstate 15 in northern Arizona are currently the subject of a study involving visual inspection, load testing, long-term instrumentation and remote health monitoring. The project is being funded by the Arizona Department of Transportation (ADOT) through a FHWA Accelerated Innovation Deployment Grant.
The steel bridges currently exhibit widespread fatigue cracking. The purpose of the project is to use state-of-the-art structure health monitoring technologies to provide information that will ensure the safety of the traveling public and provide better information to assist ADOT with short and long-term decision making about these significant bridges.
Join B&N’s Ed Cinadr for a status update on the project that started in 2016 and will continue through 2018. His presentation will include a discussion of the history of the bridges, visual inspection efforts and documentation, analytical modeling work, load testing and instrumentation, instrumentation selection, fatigue analysis, site challenges, and long-term monitoring plan.
