ABSTRACT
Theoretical and experimental investigation (ambient vibration tests and permanent monitoring system) on the structural behavior of a curved cable-stayed bridge is presented in the paper. The quoted bridge was erected in the Commercial Harbor of VeniceMarghera, Italy, and opened to traffic on January 2007. The bridge is characterized by six curved spans, of which the main two of 105 m and 126 m are cablestayed, with the stays arranged on a single plane and connected to the centerline of the composite steel and concrete deck. Furthermore, the pre-stressed concrete pylon is single and inclined. As a consequence of the spatial structural arrangement, the dynamic behavior of the deck appears very complex both in bending and torsion.
