REMOTE MONITORING OF THE INFRASTRUCTURE

Northwestern University's Infrastructure Technology Institute (ITI) engineers perform demonstration projects for bridge owners with such advanced techniques as acoustic emission (AE) and strain monitoring, time domain reflectometry (TDR), ultrasonic imaging, and impulse echo. These projects serve to acquaint bridge owners with the capabilities of these technologies as well as provide valuable field experience for the researchers developing these tools. Recently, efforts have concentrated on development of practical remote monitoring techniques that allow bridge owners to maintain close scrutiny of critical structures without the need for inspectors to actually visit the site. This paper provides an overview of efforts to integrate nondestructive evaluation technology with telemetry to allow continuous remote monitoring. These efforts represent the first step toward the development of the "smart bridge."
