In this paper, a methodology for integrating a monitor and its warning system with results from both truckload
tests and structural analysis is presented for the Jeremiah Morrow Bridge. Wireless data collection system, data
cleansing and archiving procedures, linear regression prediction model, and capacity rating based upon truckload
test results for the instrumented members are detailed. The truckload test and monitored responses document the
“normal” or expected behavior of the structure to traffic and environment, respectively. A warning system is then
designed upon a threshold technique which minimizes the probabilities of false alarms and the missed detection
of critical events based upon the capacity rating. Past results of the implemented system for the Jeremiah Morrow
and other bridges are discussed. Alarm scenarios are reviewed based upon the collected historical data from the
monitors and generated warnings.
