In order to locate damage posotion and quantify damage degree of transmission tower, the method of damage identification of transmission tower based on flexibility matrix and signalterm amplitude vector was proposed, by combining flexibility matrix method of damage identification and time-frequency analysis method of domain vibration signal. Firstly, the coefficient equation about modal parameters and damage parameters was established, according to the linear relationship between flexibility matrix elements and structure parameters. Then, by Wigner-Ville Distribution (WVD) signalterm analytical deduction of free vibration response of the damping structure, the responding function relation between signalterm amplitude and model parameters was founded. Finally, the coefficient equation was solved by substituting mode shape vector with signalterm amplitude vector, avoiding the structural modal parameters identification, the damage location and extent of transmission tower was detected once and for all. The numerical example analysis of single tower model and tower-line system shows that, the proposed method with good anti-noise performance can accurately detect the extent of single or multiple damage of current structure by a single measurement.
