approach was applied to simulated data from a numerical model of the Emerson bridge
under ambient excitation that is modeled as a stationary broadband force. The technique
was successfully used to identify modal parameters of the structure for the different sensor
configurations. The results indicated that fewer sensors resulted in the identification of
fewer modes.
Future investigations will consider a broader class of ambient vibrations, and use the modal
parameters to identify structural parameters for damage detection. More information
