This document specifies performance test procedures to determine the passive safety properties of support structures such as lighting columns, sign posts, signal supports, structural elements, foundations, detachable products and any other components used to support a particular item of equipment on the roadside. This document provides a common basis for the vehicle impact testing of items of road equipment support structures. This document does not apply to road restraint systems.

Modifications to 1.1, Scope of prEN 1990-1

In the title of the Clause, replace EN 1990 with prEN 1990-1.

Add a new paragraph (2), then have the following subclauses automatically renumbered:

“(2) This document is also applicable for existing structures, with the additional provisions given in prEN 1990-2.”

Replace the new paragraph (3) and (4) with:

“(3) This document is intended to be used in conjunction with the other Eurocodes for buildings and civil engineering works, including temporary structures.

(4) This document describes the basis for structural and geotechnical verification according to the limit state principle.”

Delete the old paragraph (5):

“(5) This document is also applicable for:

— structural assessment of existing structures;

— developing the design of repairs, improvements and alterations;

— assessing changes of use.

NOTE Additional or amended provisions can be necessary.”

Replace the paragraph (6) with:

“(6) This document is also applicable for structures where materials or actions outside the scope of EN 1991 (all parts) to EN 1999 (all parts) are involved.

NOTE In this case, additional or amended provisions can be necessary.” 

(1) This document provides provisions for the assessment of existing structures, including geotechnical structures, and the general principles for interventions, to be used in conjunction with prEN 1990-1. NOTE This document is based on the general requirements and principles of structural reliability provided in prEN 1990-1.

(2) Unless otherwise specified, prEN 1990-1 applies.

(3) This document covers general principles regarding actions for assessment, complementing EN 1991 (all parts).

NOTE Provisions for seismic actions due to earthquake are provided in EN 1998-3.

(4) This document does not cover the design of new structural parts that will be integrated into an existing structure.

NOTE For the design of new structural parts, see prEN 1990-1.

(5) This document does not provide:

— specific rules for initiation of assessment;

— specific rules on how to undertake interventions that may be carried out as a result of an assessment;

— material-specific technical provisions for existing structures;

— provisions for seismic assessment and retrofitting of existing structures.

NOTE For provisions for seismic assessment and retrofitting of existing structures, see EN 1998-3.

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.

ISO 13473-5:2009 specifies procedures for determining the average depth or level of pavement surface megatexture by measuring the profile curve of a surface and calculating megatexture descriptors from this profile. The technique is designed to give meaningful and accurate measurement and description of pavement megatexture characteristics for various purposes. Since there is an overlap between megatexture and the surrounding ranges, the megatexture descriptors unavoidably have a certain correlation with corresponding measures in those ranges. ISO 13473-5:2009 specifies measurements and procedures which are in relevant parts compatible with those in ISO 13473-1, ISO 8608 and EN 13036-5.
