An interpretation of dynamic testing carried out on a curved multi-span post-tensioned reinforced concrete viaduct is presented in this paper. The viaduct has been recently built in the new highway line connecting the cities of Pordenone and Conegliano (North-Eastern Italy). Output-only vibration tests under traffic loads were carried out to extract the dynamic pa-rameters of the lower vibration modes of the structure. A comparison between experimental data and numerical results obtained from a preliminary finite element model of the viaduct is pre-sented and discussed.

Abstract
An interpretation of dynamic testing carried out on a curved multi-span post-tensioned reinforced concrete viaduct is presented in this paper. The viaduct has been recently built in the new highway line connecting the cities of Pordenone and Conegliano (North-Eastern Italy). Output-only vibration tests under traffic loads were carried out to extract the dynamic pa-rameters of the lower vibration modes of the structure. A comparison between experimental data and numerical results obtained from a preliminary finite element model of the viaduct is pre-sented and discussed.File in questo prodotto:
