A structural dynamic propertiesbased damage identification method was proposed. The dynamic response of the uniform BernoulliEuler beam was discussed by introducing a damage distribution function, and a “damage influence matrix(DIM)" was constructed, which can show the structural modal coupling induced by damage. The method of structural damage location and assessment based on DIM was also introduced.
