Foreword
This European Standard EN 1993-1-11, Eurocode 3: Design of steel structures: Part 1-11 Design of structures with tension components, has been prepared by Technical Committee CEN/TC250 « Structural Eurocodes », the Secretariat of which is held by BSI. CEN/TC250 is responsible for all Structural Eurocodes.
This European Standard shall be given the status of a National Standard, either by publication of an identical text or by endorsement, at the latest by April 2007 and conflicting National Standards shall be withdrawn at latest by March 2010.
This Eurocode partially supersedes ENV 1993-2.
According to the CEN-CENELEC Internal Regulations, the National Standard Organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
National annex for EN 1993-1-11
This standard gives alternative procedures, values and recommendations with notes indicating where national choices may have to be made. The National Standard implementing EN 1993-1-11 should have a National Annex containing all Nationally Determined Parameters to be used for the design of tension components to be constructed in the relevant country.
National choice is allowed in EN 1993-1-11 through: – 2.3.6(1) – 2.3.6(2) – 2.4.1(1) – 3.1(1) – 4.4(2) – 4.5(4) – 5.2(3) – 5.3(2) – 6.2(2) – 6.3.2(1) – 6.3.4(1) – 6.4.1(1)P – 7.2(2) – A.4.5.1(1) – A.4.5.2(1) – B(6)

1 General 1.1 Scope
(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 locked coil rope B circular wire and stranded wire strand rope circular wire parallel wire strand (PWS) circular wire bundle of parallel wires C 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 banisters, balconies, bridge rails and guardrails
Fully locked coil ropes are fabricated in the diameter range of 20 mm to 180 mm and are mainly used as – stay cables, suspension cables and hangers for bridge construction – suspension cables and stabilizing cables in cable trusses – edge cables for cable nets – stay cables for pylons, masts, aerials

EN 1993-1-11: 2006 (E)
5 Structural strand ropes are mainly used as – stay cables for masts, aerials – hangers for suspension bridges – damper / spacer tie cables between stay cables – edge cables for fabric membranes – rail cables for banister, balcony, bridge and guide rails.
NOTE 3: Group C products need individual or collective anchoring and appropriate protection. Bundles of parallel wires are mainly used as stay cables, main cables for suspension bridges and external tendons. Bundles of parallel strands are mainly used as stay cables for composite and steel bridges.
(4) The types of termination dealt with in this part for Group B and C products are
– metal and resin sockets, see EN 13411-4 – sockets with cement grout – ferrules and ferrule securing, see EN 13411-3 – swaged sockets and swaged fitting – U-bolt wire rope grips, see EN 13411-5 – anchoring for bundles with wedges, cold formed button heads for wires and nuts for bars.
