报告摘要：

This talk focuses on applications of Bayesian approach in solving inverse problems in the area of damage detection and modal identification. One of the advantages of the Bayesian approach is that it not only identifies the results but also quantifies the associated uncertainties. The talk first reviews Bayesian statistical framework and Bayesian modal class selection method, and then discusses their applications in vibration-based and guided wave-based damage detection problems done by the speakers in last couple of years. The second part of the talk focuses on using the Bayesian approach in solving the modal identification problems, in particular, the forced vibration modal identification is the focus. After that the validation and application of a newly developed uncertain law for planning and managing uncertainties of known-input modal identification are presented and discussed.
