Abstract :
Hilbert-Huang transform (abbr. as HHT) signal treatment method has been applied in the vibration signal analysis of bridge structural health monitoring system in this article. Through Empirical Mode Decomposition (abbr. as EMD) and the HHT over the vibration signals that are collected from the Hangzhou Xiasha Bridge structural health monitoring system, the Hilbert boundary spectrum has been obtained. In each one of the single step conducted during the whole process of analysis over the dynamic characteristics of the bridge vibration signals, the final results have approved the applicability and effectiveness of the HHT method in the analysis of bridge vibration signals.
