Structural Testing and Monitoring of the I-15 Virgin River Bridges
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 purpose of the project is to utilize 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 in short and long term decision making about these significant bridges. The steel bridges currently exhibit widespread fatigue cracking.
The presentation will provide a status update on the project which began in 2016 and will continue through 2018. The discussion also will include a history of the bridges, visual inspection efforts and documentation, analytical modeling work, load testing and instrumentation, instrumentation selection, fatigue analysis, site challenges, and the long term monitoring plan.
