Abstract
The extensive discussion about OMA algorithms and tools for validation and postprocessing of modal identification results represents the background of the present chapter that is focused on a number of explanatory applications, including some special issues. Most of the reported applications refer to real experimental tests, which have been selected as representative of frequently tackled issues in modal testing and data processing. In particular, they illustrate a possible approach to assess the capability of the measurement chain of fitting the requirements of a specific application, methods for accurate estimation of damping ratios, and methods for identification of spurious harmonics. Additional examples concern the possible uses of the identified modal parameters, such as numerical–experimental correlation and tuning of a numerical model, development of empirical correlations for the estimation of the fundamental natural frequencies of selected typologies of structures, the estimation of modal masses by mass change methods. As a result, the present chapter provides a definite overview of opportunities and limitations of OMA and a guide for applications.
