Abstract
Over the years different methods have been proposed for how to deal with the presence of harmonic components in operational modal analysis. In this paper a method for detection of harmonic components using Fast Kurtosis Checking will be introduced along with a new frequency domain curve-fitting version of the Enhanced Frequency Domain Decomposition (EFDD) technique. This combined approach makes it possible to extract structural modes fast even when several harmonic components are present and even when the harmonic components are located exactly at the natural frequencies of the structural modes. The applicability of the combined approach is assessed for a case within mechanical engineering as well as a case within civil engineering.
