Abstract

In the industry, the damage detection of stayed cable is an important research subject. A proper method for the vibration signal processing is indispensable. The Hilbert-Huang Transform (HHT), which has been successfully applied to many different fields in the last ten years, may provide a promising method for this purpose. The purpose of this research is to detect the crack on beams by HHT of transient flexural waves. The mean values of absolute relative error are all less than 2.5%. In addition, the characteristics on Hilbert spectrum of the damage size were also studied. This study may contribute to the damage size estimation in the near future.
