Subject RIV JM - Building Engineering R&D Projects GA103/09/0091 GA ČR - Czech Science Foundation (CSF) CEZ AV0Z20710524 - UTAM-F (2005-2011) Annotation Downtrend of the fundamental natural frequency of a structure with time, detected by periodical diagnostic in situ measurements, can signal damage, starting anywhere in the structure, or the progressing degradation of its material. The influence of aging (creep) of concrete on E-modulus is examined in the paper, using the data found on a real chimney during the first 7 years of its existence. An attempt to use these data for the prognosis of the future behaviour of this structure was given a half year ago; the presented paper brings recent results obtained on other old RC structures, newly tested after some years.
