During the October 2000 flood almost all the watercourses in the province of Turin that were tributaries of the Po river underwent exceptional high waters and consequent flooding, which caused enormous economic and environmental damage.
During the October 2000 flood almost all the watercourses in the province of Turin that were tributaries of the Po river underwent exceptional high waters and consequent flooding, which caused enormous economic and environmental damage. Afterward the province of Turin appropriated considerable funds to set the riverbeds to rights and to reconstruct the damaged infrastructures, among which the Sangone creek bridge. This sixty-metre-long three-masonry-arch bridge, located in the town of Giaveno, in fact collapsed during the high water of October 16th 2000. The impossibility of changing the existing highway route, owing to the numerous constructions lined along it, compelled design to conserve the old bridge’s position in both line and grade, and this was a heavy constraint on the design of the new one.
At the end the choice fell on an eighty meters long single-span cable-stayed bridge. The deck cross section, a total 15.10 wide, is the classical one for small-span stayed bridges: there are two main girders, of rectangular section 2.0 m. x 1.20 m., in situ-poured and lightly prestressed on whose centrelines are anchored the stays, with their heads placed in special places. The two longitudinal beams bear the secondary crosswise weave, created with adherent-strand prestressed precastings placed at 2.50 m. spacings. The pylon, a total 37 m. high from its springer, consists of two blade uprights inclined by ten degrees to the vertical, and connected by an upper prestressed crosspiece, placed immediately below the stay anchorages. The pylon bears eight pairs of stays that sustain the eighty-meter span and is itself anchored to the ground by another four pairs of stays that are anchored on the mooring block. The pylon base is a caisson foundation structure, such as to directly transfer the stresses below the creek bed directly onto the bedrock.
