There is a good correlation among the modal parameters identified from the three independent identification techniques.
The aim is to provide a degree of confidence in the modal parameters identified.
Three sets of damage identification results are obtained using modal parameters identified based on ambient, 0.03 g, and 0.05 g RMS white noise test data, respectively.
The modal parameters identified by the EMD-HT method from the bridge responses recorded at different locations are compared with each other to check their consistency.
The present identification method demonstrates its full effectiveness in detecting both flexible- and fixed-base modal parameters identified based on earthquake excitation, also in the presence of close modes and heavy damping (in terms of identification challenge).
A Monte-Carlo simulation is performed on a simply supported beam, and the uncertainty on a set of 5000 modal parameters identified with the stochastic subspace identification method is discussed.
