Abstract
In order to inspect the safety of buildings or structures when they are damaged, a non-destructive inspection is required to identify the location and the degree of damage. One of the analysis methods for such identification inverse problems is the physical properties identification method using filtering theory. This report, as an application example, examines the validity of this method based on specific numerical calculation samples, together with formulating the analysis algorithm, using the multiple damage identification problem of a beam structure as the subject.
