A two-stage framework for automated operational modal identification
Structure and Infrastructure Engineering, 2021 Automated operational modal analysis (OMA) is attractive and has been extensively used to replace traditional OMA, which requires much empirical observation and engineers’ judgment.

Machine‐learning‐based methods for output‐only structural modal identification [PDF]
Structural Control & Health Monitoring, 2020 In this study, we propose a machine‐learning‐based approach to identify the modal parameters of the output‐only data for structural health monitoring (SHM) that makes full use of the characteristic of independence of modal responses and the principle of ...
