The research aims to present Modalyzer, a Python library for operational modal analysis tailored for structural health monitoring.
Implementation of various OMA techniques in Modalyzer, including EFDD, SSI-COV, SSI-DATA, PolyMAX, and ITD.
Applications to three different case studies to demonstrate flexibility and robustness.
Comparison of results obtained from Modalyzer with independent calculations for validation.
Modalyzer shows significant time efficiency compared to traditional tools like ARTeMIS Modal.
Strengths and limitations of each OMA method are identified across different structural conditions.
Guidance is offered for selecting the appropriate OMA technique for specific SHM scenarios.
