ÖNORM EN 1993-1-11

(1) prEN1993-1-11 gives design rules for structures with tension components made of steel, which, due to their connections with the structure, are adjustable and replaceable see Table 1.1. NOTE: Due to the requirement of adjustability and replaceability such tension components are generally prefabricated products delivered to site and installed into the structure. Tension components that are not adjustable or replaceable, e.g. air spun cables of suspension bridges, or for externally post-tensioned bridges, are outside the scope of this part. However, rules of this standard may be applicable. (2) This standard also gives rules for determining the technical requirements for prefabricated tension components for assessing their safety, serviceability and durability. Table 1.1: Groups of tension components Group Main tension element Component A rod (bar) tension rod (bar) system, prestressing bar circular wire spiral strand rope circular and Z-wires fully B locked coil rope circular wire and stranded wire strand rope circular wire parallel wire strand (PWS) C circular wire bundle of parallel wires seven wire (prestressing) strand bundle of parallel strands NOTE 1: Group A products in general have a single solid round cross section connected to end terminations by threads. They are mainly used as bracings for roofs, walls, girders stays for roof elements, pylons tensioning systems for steel-wooden truss and steel structures, space frames NOTE 2: Group B products are composed of wires which are anchored in sockets or other end terminations and are fabricated primarily in the diameter range of 5 mm to 160 mm, see EN 12385-2. Spiral strand ropes are mainly used as stay cables for aerials, smoke stacks, masts and bridges carrying cables and edge cables for light weight structures hangers or suspenders for suspension bridges stabilizing cables for cable nets and wood and steel trusses hand-rail cables for b (...abbreviated)
