Description
  • Na lávce pro pěší přes dálnici D5 u Černic, která byla navržena firmou PONTEX Ltd., byla provedena experimentální modální analýza. Jejím hlavním cílem bylo určit charakteristiky vlastního kmitání lávky pro ověření dynamického výpočtu a pro případný návrh pohlcovače kmitání. Během experimentální modální analýzy bylo určeno devět vlastních frekvencí lávky ve frekvenčním rozmezí 0,5 - 10,0 Hz. Útlum a tvary vlastního kmitání lávky byly určeny pouze pro vlastní kmitání vodorovné nosné konstrukce. Experimentálně určené frekvence a tvary vlastního kmitání lávky byly porovnány s frekvencemi a tvary určenými dynamickým výpočtem. (cs)
  • An experimental modal analysis was carried out on a new footbridge across the highway D5 near Cernice, which was designed by PONTEX Ltd. The main aim of this analysis was to estimate characteristics of natural vibration of the investigated bridge structure to verify the dynamic design and to use modal parameters for the possible design of the tuned mass absorber. During experimental modal analysis nine natural frequencies were evaluated within the frequency range 0.5 - 10.0 Hz. Natural modes and damping were evaluated only for frequencies of natural vibration of a horizontal bearing structure. Experimentally estimated natural frequencies and mode shapes were compared with frequencies and mode shapes computed in the dynamic design of the footbridge.
