Abstract
The endeavour to use the changes of dynamic characteristics for the
determination of damage or other imperfections of structures is not new. The
rudimentary application of structural evaluation and damage assessment by
vibration monitoring has been practiced since ancient times. Ancient potters
knocked on their vases to make sure they were free of cracks or voids.
Experimental work in the field of modal analysis of real structures from
the 70s and 80s of last century (offshore oil drilling platform [I]). Modal
analysis was used also in the laboratory tests of plastics [2]. Identification of
damages of R.C. bridges by means of frequency spectra of response are known
from the 90s [8], [9]. A survey of the development of identification methods can
be found in [3].
