Resumé

The Frequency Domain Decomposition (FDD) technique is known as one of the most user friendly and powerful techniques for operational modal analysis of structures. However, the classical implementation of the technique requires some user interaction. The present paper describes an algorithm for automated FDD, thus a version of FDD where no user interaction is required. Such algorithm can be used for obtaining a default estimate of modal parameters in commercial software for operational modal analysis - or even more important - it can be used as the modal information engine in a system for structural health monitoring
