ABSTRACT

This paper relates the about the exhaustive campaign of analysis and tests carried out in order to retrofit the structure of the ‘‘Incoronata’’ viaduct along the Salerno-Reggio Calabria highway in southern Italy. The work carried out has allowed to effectively estimate the reliability and performances the bridge as well as to identify an effective solution for the upgrade of the structure. This upgrade being necessary in order to obtain an increase in bearing capacity in terms of both live and seismic load, and to modify the geometry of the bridge. In particular, the extensive analyses carried to obtain a complete knowledge of the bridge in its present condition may represent a significant example of structural reliability and performance assessment.
