Civil engineering structures in operation are likely to suffer damage. During the service life,
structural damage evolves gradually from minor to severe. However, most current studies …

To improve the mode decomposition capacity of the empirical Fourier transform for time-
varying structures, an empirical multi-synchroextracting decomposition method has been …

Structural systems often exhibit time-varying dynamic characteristics during their service life
due to severe hazards and/or environmental erosion. Therefore, the identification of time …
