Experimental and theoretical analysis of viaduct valtura

The paper addresses static and dynamic testing of viaduct Valtura. Statical testing was carried out through 9 loading phases, in which 6 heavy trucks were used. In the course of statical loading displacements were measured in the middle and at supports of each span. In determination of dynamical parameters of structure methods of operational modal analysis were implemented, natural frequencies, modal shapes and damping ratios were determined for fundamental modes. Statical and dynamical numerical analysis of the structure was also conducted using finite element model of the structure. Results of experimental testing are directly compared to results of numerical analysis.
