San Giuliano Footbridge, Mestre
The bridge gives access to the new San Giuliano Park , facing the lagoon in front of the city of Venice. It overpasses a road roundabout, covering 145 m in two spans.
The steel bridge features a central mast and a stayed deck, composed of two lateral caisson beams connected by transversal girders supporting a timber floor. The mast is stabilized by lateral guys. The structure is connected to the concrete abutments by tubular struts; longitudinal movements of the deck are allowed, while bending moments are restrained and the outer stays are also restrained by a connection to the abutments.
Dynamic vibration control is achieved by tuned mass dampers installed inside the main beams.
