Abstract

Effective structural model updating and damage identification methods are proposed by using incomplete measured modal data. The exact relationship between the perturbation of structural parameters and the modal properties of the tested dynamic structure is given on the base of dynamic perturbation method. Structural perturbation parameters are properly selected to represent the differences in structural parameters for structural model updating and damage identification at critical point level. Experimental studies for a laboratory tested steel structure model are undertaken to verify the effectiveness of the proposed model updating technique and to investigate the influence of structural damage on changes of modal parameters. Furthermore, a cable-stayed bridge is adopted for numerical investigations on inverse structural damage identification. The results from experimental studies and numerical investigations show the applicability of the proposed method to structural model updating and damage identification. © 2014 Taylor & Francis Group.
