Abstract
Podajamo numerično oceno vibracijskih oblik desnega objekta viadukta Ravbarkomanda. V ta namen je bil narejen detajlen numerični model konstrukcije po metodi končnih elementov. Togost prekladne konstrukcije je bila kalibrirana glede na izmerjene specifične deformacije nosilcev med testnimi prehodi težkih vozil. Prikazani rezultati bodo v pomoč pri načrtovanju vibracijskih testov na tem pomembnem avtocestnem objektu.

Title:Numerical evaluation of dynamic characteristics of the Ravbarkomanda viaduct
Abstract:
A numerical estimation of the vibration modes of the right part of the Ravbarkomanda viaduct is presented. To this end, a detailed finite element model of the structure was prepared. The stiffness of the deck was calibrated according to the strains in the beams, measured during the test passages of heavy vehicles. The presented results will be used for the design of vibration tests on this important Slovenian motorway facility.

Keywords:Ravbarkomanda viaduct, finite elements, stiffness calibration, eigenfrequencies, eigenmodes
