Blind modal identification of output-only structures in time-domain based on complexity pursuit
2013
Earthquake engineering & structural dynamics (Print)
Output-only modal identification is needed when only structural responses are available. As a powerful unsupervised learning algorithm, blind source separation (BSS) technique is able to recover the hidden sources and the unknown mixing process using only the observed mixtures. This paper proposes a new time-domain output-only modal identification method based on a novel BSS learning algorithm, complexity pursuit (CP). The proposed concept-independent 'physical systems' living on the modal
