1.1 Scope of EN 1993-1-11 (1) EN 1993-1-11 provides rules for structural design of tension components made of steel, in addition to other parts of EN 1993, for use in structures made of steel or other materials such as concrete, steel-concrete composite and timber. (2) EN 1993-1-11 covers the resistance, serviceability and durability of steel tension elements. (3) The following items/aspects are outside the scope of EN 1993-1-11: - pre- or post-tensioned systems in accordance with EN 1992-1-1 and EN 1992-2; - reinforcing steel as part of a concrete structure in accordance with EN 1992-1-1; - tension components in piling; - detailed design of terminations. 1.2 Assumptions (1) Unless specifically stated, EN 1990, EN 1991 and the EN 1993-1 series apply. (2) The design methods given in EN 1993-1-11 are applicable if: - execution quality is according to EN 1090-2; and - the construction materials and products used are as specified in the relevant parts of the EN 1993 series, or in the relevant material and product specifications. (3) EN 1993-1-11 is used in conjunction with ENs, EADs and ETAs for tension components.

(1) EN 1993-2 provides a general basis for the structural design of steel bridges and steel parts of composite bridges. It gives provisions that supplement, modify or supersede the equivalent provisions given in the various parts of EN 1993-1. (2) The design criteria for composite bridges are covered in EN 1994-2. (3) The design of high strength cables and related parts are included in EN 1993-1-11. (4) This European Standard is concerned only with the resistance, serviceability and durability of bridge structures. Other aspects of design are not considered. (5) For the execution of steel bridge structures, EN 1090 should be taken into account. NOTE: As long as EN 1090 is not yet available a provisional guidance is given in Annex C. (6) Execution is covered to the extent that is necessary to indicate the quality of the construction materials and products that should be used and the standard of workmanship needed to comply with the assumptions of the design rules. (7) Special requirements of seismic design are not covered. Reference should be made to the requirements given in EN 1998, which complements and modifies the rules of EN 1993-2 specifically for this purpose.

EN 1994-2 gives design rules for steel-concrete composite bridges or members of bridges, supplementary to the general rules given in EN 1994-1-1.
