KEYWORDS

ABSTRACT

Structural health monitoring field had been concerned by researcher since it was realized that structural failure might be caused by degradation of structural strength. Some methods related to dynamic analysis, had been developed to establish the damage location. One of them is FRF curvature difference method which can exact locate the damage. From numeric analysis, it can be concluded that variability of damage level and excited of this method is not sensitive to damage location. However, the magnitude of FRF curvature difference is sensitive to them.
