| Abstract: | The void detection method based on Hilbert-Huang Transform in Concrete Filled Steel Tube(CFST) was proposed.The acoustic vibration signal for CFST with transient impact was analyzed.The instantaneous amplitude feature samples were extracted,and the improved K-means clustering method was used to do second-class pattern recognition for the feature samples.Thus the void in CFST was judged.The result shows this method is feasible. |
