Case studies on Vibration Based Damage Identification: Multi-criteria Approach

摘要：

Vibration based damage identification methods examine the changes in primary modal parameters or quantities derived from modal parameters.As one method may have advantages over the other under some circumstances, a multi-criteria approach is proposed.Case studies are conducted separately on beam,plate and plate-on-beam structures.Using the numerically simulated modal data obtained through finite element analysis software, algorithms based on flexibility and strain energy changes before and after damage are obtained and used as the indices for the assessment of the state of structural health.Results show that the proposed multi-criteria method is effective in damage identification in these structures.
