This paper proposes a nondestructive testing technique based on modal analysis in order to develop a new, efficient and simple damage detection method for civil structures. Structural identification for health monitoring involves comparison of changes in structural properties or response, and it can be viewed as pattern classification problems. However, a very large database is required to stor...

The existence of damage in different members of a structure can be posed as a fault detection problem. It is also necessary to isolate structural members in which damage exists, which can be posed as a fault isolation problem. It is also important to detect the time instants of occurrence of the faults/damage. The structural damage detection filter developed in this paper is a model-based fault...
