Identification of modal parameters of long-span bridges under various wind velocities

Identification of modal parameters of long-span bridges under various wind velocities

Abstract The modal parameters identification of bridges under non-stationary environmental excitation has caught the attention of researchers. This paper studies the non-stationarity of wind velocity, and extracts the time-varying mean wind velocity based on a discrete wavelet transform and recursiv...
