Abstract: An
instrumentation system was implemented on the Powder Mill Bridge in Barre,
Massachusetts. The instrumentation was designed as a research prototype for development
of a structural health monitoring system. Strain data from permanently installed strain
gauges was collected for truck events over a period of six months. Maximum strain values
from heavy truck events were used to ... read moreestablish statistical distributions which describe
behavior of the undamaged bridge under normal operating conditions. Prediction intervals
were added to the statistical distributions. A calibrated finite element model of the
bridge was used to simulate damage scenarios, including large scale and localized damage
of the bridge deck. Analytical distributions of a damaged bridge model were plotted
against experimental distributions of the undamaged bridge with prediction intervals. It
was shown that, given 1500 future heavy truck events, all three damage scenarios studied
would be detectable.
