Dynamic behavior of a cable-stayed footbridge over river Vrbas in Banja Luka
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.
