This document provides a summary of the damage identification study on the Dowling Hall Footbridge through deterministic and probabilistic finite element (FE) model updating. The footbridge is located at Tufts University and is equipped with a continuous monitoring system that measures its ambient acceleration response. In this study, effects of physical damage are simulated by loading a small ... read moresegment of the footbridge deck with concrete blocks. The footbridge deck is divided into five segments in a FE model of the test structure and the added mass on each segment is considered as an updating parameter. The damage identification results are found to be in good agreement with the simulated damage on the bridge.read less
