Theoretical justification of natural frequency identification in the FDD (Frequency Domain Decomposition) method
This paper is the first to provide a justification for the main criterion of the Frequency Domain Decomposition (FDD) algorithm based on the singular value decomposition of a spectral measured signals’ density. The algorithm is used for monitoring the structures such as buildings, bridges, dams, to...
