ABSTRACT:
A corrosion-resistant tension member, particularly an inclined cable of a cable stayed bridge, is comprised of a bundle of individual elements, for example, steel wire strands, which in the open area is encapsulated by sheathing, and which in the area of a rerouting point, for example, at the pylon of a cable-stayed bridge, extends inside a saddle pipe in a canal having the shape of a circular arc. In order to avoid impairments at the ends of the saddle pipe when sheathing is connected to the structure, the saddle pipe is extended in the shape of a circular arc beyond a tangential exit of the bundle by a length L so that the bundle is exposed at an end of the saddle pipe without any risk of abutting.
