Abstract

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, Eigen vector 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.
