Abstract EN
A damage location method based on cross correlation function, wavelet packet decomposition, and support vector machine was proposed for grid structure.
The approximate damage positions in grid structures could be determined through the peak abrupt changes of the cross correlation function that was produced by two vibration responses of adjacent measuring points.
The vibration response was decomposed into eight bands by wavelet packet in order to accurately locate damage rods.
The energy distribution in eight bands was used as a feature vector.
SVM is trained to locate damaged bar elements in grid structures.
Numerical analysis results showed that this method had good accuracy.
