Cable-stayed bridge over the River Pinheiros
published: 13 04 2000
This structure, located over a new metro line and the River Pinheiros in Sao Paulo
This structure, located over a new metro line and the River Pinheiros in Sao Paulo, is a cable-stayed, mass-transit railway bridge with two lines and boasts the novel feature of supporting a Metro station on the main span.
The total length is 231m (35m - 50m - 122m - 23m), the smaller span of 23m specifically designed to reduce deformations in the structure under moving loads.
The deck is a pre-stressed concrete, single-cell box girder 2.5m high, with the 122m main span being constructed by the balanced cantilever method.
The cable staying is in a single plane located on the centreline: the pylon is 53m over the deck level. There are 34 stay cables: 17 of which are spaced at 4.55m intervals on the 35m. and 50m. length counter-balancing spans, and 17 are spaced at 6.5 m over the main span.
The upper extremities of the cables are anchored on the single pylon in horizontally prestressed concrete, whereas the lower extremities are anchored on the axial ribbing of the box girder's upper decking. The cables, ranging from 33 to 55 strands, consist of hot-dip galvanised, 7-wire 15.7 mm. diameter strands, HDPE coated and wax injected. The cables are protected by light grey HDPE sheathing, with an externally welded HDPE helicoidal rib, designed to minimize oscillations due to the combined action of wind and rain.
The anchorages underwent a series of static and fatigue tests performed at the laboratories of Bochum University (Germany). The fatigue test was carried out over 2 million cycles, with the upper load equal to 45% of the ultimate strength and the dynamic variation at 200N/mm2.
