Abstract
This paper presents an investigation of structural damage identification with various uncertainty conditions. The model-based damage identification techniques compare the change of the identified model and the change of the analytical model, such as a finite element model, due to damage. The analytical model is different from the identified model because of errors from boundary conditions, material properties, and other variability. The uncertainty associated with identification errors and other random factors may also result in false indications of damage. In this study, we examine the damage identification with various uncertainties, such as boundary condition variation, temperature change, and environmental variation. Experiments of a beam structure under various uncertainties will be used to demonstrate the study.
