Modal analysis of the Dubrovnok bridge
This paper presents the testing results of natural frequencies of "The Dubrovnik Bridge" superstructure and the natural frequencies of each cable. The measuring was carried out using a very fast A/D converter of Picolog-ADC216 type, with a 16-bit resolution. PC portable computer and Pico-Scope software with FFT analyzer were used in experimental analysis. Theoretical analysis of natural frequencies of the superstructure was carried out using the finite element method with the Sofistik software. The results are directly compared graphically and tabularly. Measured natural frequencies of the cables were used to determine cable forces which were then compared with the forces from the last protocol of prestresing during construction. Very good agreement is found between compared theoretical and experimental results.
