Description	Two, full size, reinforced concrete frames were put on a shaking table and underwent seismic excitations with increasing intensities. The aim of the reported experiment was to study changes in their dynamic, modal parameters due to development of cracks in concrete. Dynamic identification of these frames was carried out through diagnostic tests interlaced with the damaging excitations. This paper presents the results of their identification in various states of damage, using low level non-destructive damage estimation methods. A characteristic decrease of natural frequencies and an increase of structural damping was observed.

(en) Článek popisuje experimenty vedoucí ke sledování změn dynamického chování a modálních charakteristik na poškozeném železobetonovém rámu. Dynamická identifikace rámů byla založena na diagnostických testech spojených se zatěžováním konstruikce s různou intenzitou. Byly pozorovány některé charakteristické jevy. (cs)
