Connecticut Permanent Long-Term Bridge Monitoring Network Volume 3: Monitoring of a Multi-Steel Girder Composite Bridge – I-91 SB over the Mattabesset River in Cromwell (Bridge #3078)

This report describes the instrumentation and data acquisition for a multi-girder, composite steel bridge in Connecticut. The computer-based remote monitoring system was developed to collect information on the girder bending strains. The monitoring system was installed in 2004 to collect girder strains. The bridge is part of a network of bridges in a long-term research project to evaluate the performance of a variety of bridges in Connecticut. Data have been collected over a multi-year period using normal vehicular traffic. A series of papers has been generated to explore how the monitoring of this bridge can provide information of use to the Department of Transportation. The initial study involved the development of the data collection approach, used load tests and finite element analyses to describe the behavior, and used the data to make comparisons with the AASHTO Specification Requirements. The next study continued the development of the data from normal truck traffic to determine load and patterns and to propose guidelines for the long-term structural health monitoring of this bridge. The third study demonstrated that the monitoring system can also be used as a Bridge Weigh-In-Motion system. The monitoring system serves as a nonintrusive system to provide information on both the quantity and weights of trucks crossing the bridge. In the next study damage measures were developed for this bridge and compared to the inherent variability of actual bridge measurements to determine the minimum level of damage that can be detected by the system. The final study described in this report identifies and quantifies different data qualification measures needed for the structural health monitoring of this bridge.
