Abstract

This paper presents a dynamic behavior analysis of an old cable-stayed footbridge over river Vrbas
in Banja Luka. Identification of modal parameters, of this prone to vibrations footbridge structure,
was performed using Operational Modal Analysis with Frequency Domain Decomposition method.
Experimental test setups and obtained results, compared to the numerical values obtained by FE
model updating, are shown. Modal Assurance Criterion was used for the confirmation of the
uniqueness of experimentally obtained mode shapes, and also for the comparison of FE model mode
shapes to the experimentally obtained ones, in the locations of measurement.
