Description
In this study, we deal with a method for damage identification of composite girder bridges based on the changes in the modal characteristics. Generally damage to structure causes any change in modal characteristics of the structure. From the results of modal analyses of a girder bridge with sixty damage scenarios, it became clear that the changes in the primary mode shapes of target lines have a close relation to the places and degrees of damages to the bridge. We proposed a method for damage identification of girder bridges based on the changes in primary mode shape.
