Original Abstract

The vibration analysis of the signal from piezoelectric transducer of a traffic-loaded bridge has been used to determine the eigen frequency of dynamically loaded bridge. From our results it follows that the eigen frequency of the dynamically loaded bridge by two lorries is 5.3 Hz. Increasing the bridge load causes a change of the frequency spectrum. Moving cars passing over the bridge creates vibration spectra corresponding to superposition of bridge and cars fundamental frequency and theirs higher harmonics.

Key words in English

Vibration analyses, piezoelectronic transducer, loaded bridge, eigen frequwency
