- Abstract
The dynamic characteristics of the structure (natural frequencies, forms and damping) contain data about its structural state. Changes in one of them indicate the change of the structural state (damage). As actual damage is usually hard to visualize and locate the experimental modal analysis presents a useful tool as being fast, reliable and non-destructive. Based on the changes in dynamic characteristics between two measurements it is possible to draw the conclusion about the structural state. Qualitative location of damage is relatively easy to obtain, while the quantitative extent of damage is much harder to determine. The applicable methodology for the qualitative and quantitative extent of damage has been outlined and explained on a practical example in this paper.
