Author Affiliations +
The Connecticut Department of Transportation (ConnDOT) has undertaken a major initiative to install permanent remotely- accessible monitoring systems on seven in-service highway bridges. These systems will consist of either a Roadway Weather Information System (RWIS), or Structural Monitoring System (SMS), or both, depending on the structure type and/or location. The RWIS provides weather related information regarding the pavement on and off the structure and ambient weather conditions at the bridge site. Systems like this are commercially available and in use throughout the country assisting transportation agencies in performing winter maintenance operations. The SMS is the product of cooperative research at the University of Connecticut and ConnDOT. The University has specified, installed and operated a prototype vibrational-based monitoring system on tow in-service bridges during separate year-long studies. The planned SMS, modeled after the prototype, includes accommodations for a variety of sensors including strain, tilt, structural temperature and vibration. The ultimate goal of this work is to develop a generic platform for a remote bridge monitoring system which can be adapted to any bridge with any combination of sensors and sensor types. Such a system would benefit both the safety and management of these structures. Current activity along with background information are discussed.
