Abstract: [slo] [eng]
Článok pojednáva o možnostiach merania dynamickej odozvy závesov na budenie impulzom. Uvedené sú základné vzťahy medzi silou v lane a vlastnou frekvenciou kmitania závesu a podmienky použitia týchto vzťahov na skutočnej konštrukcii. Poznatky sú následne aplikované na lávke pre chodcov v meste Napajedla. Cieľom merania bolo stanovenie veľkosti sily v závesoch, zhodnotenie ich stavu a namáhania na základe dynamickej odozvy. Paper discusses the possibilities of measuring the dynamic response of cables to impulse excitation. Basic relations between cable force and natural frequency of cable and conditions of use on real structures are mentioned. Methods are applied on a pedestrian bridge in Napajedla. The aim of the measurement was to determine the cable force and to evaluate their condition and stress based on the dynamic response.
Keywords: cable force; cross - sectional weakening; natural frequencies; pedestrian bridge; String oscilation
