Abstrakt


In this paper the experimental and numerical results of dynamic characteristics (i.e. natural frequencies and modes of vibrations) of the cable-stayed footbridge, located in Czestochowa, are presented. The numerical analysis was carried out with the ABAQUS package. The in situ tests methodology and the results are also presented on the basis of the spectral analysis of vibrations caused by a group people jumping. The theoretical and experimental results are in good agreement as far as both the natural frequencies and eigenmodes are concerned.
