THE RESEARCH OF DAMAGE DETECITION OF GIRD-SLAB COMPOSITE BRIDGE BASED ON LIFTING WAVELET ENTROPY INDEXES
Taking advantage of characteristics of lifting wavelet and entropy, the structural damage identification method based on lifting wavelet entropy is proposed in this paper. And the lifting wavelet time entropy index and the relative lifting wavelet entropy index are established. The new method and damage indexes are verified in numerical simulation of gird-slab composite bridge. The analysis results show that lifting wavelet time entropy can identify structural damage moment and the relative lifting wavelet entropy can identify structural damage location.
