Where a normative part of this EN allows for a choice to be made at the national level, the range and possible choice will be given in the normative text, and a note will qualify it as a Nationally Determined Parameter NDP. NDPs can be a specific value for a factor, a specific level or class, a particular method or a particular application rule if several are proposed in the EN.

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of an identical text or by endorsement, at the latest by November , and conflicting National Standards shall be withdrawn at latest by March This Eurocode supersedes ENV Background to the Eurocode programme In , the Commission of the European Community decided on an action programme in the field of construction, based on article 95 of the Treaty.
The objective of the programme was the elimination of technical obstacles to trade and the harmonization of technical specifications. Within this action programme, the Commission took the initiative to establish a set of harmonized technical rules for the design of construction works which, in a first stage, would serve as an alternative to the national rules in force in the Member States and, ultimately, would replace them. For fifteen years, the Commission, with the help of a Steering Committee with Representatives of Member States, conducted the development of the Eurocodes programme, which led to the first generation of European codes in the s.
The Eurocode standards provide common structural design rules for everyday use for the design of whole structures and component products of both a traditional and an innovative nature. Unusual forms of construction or design conditions are not specifically covered and additional expert consideration will be required by the designer in such cases.
National Standards implementing Eurocodes The National Standards implementing Eurocodes will comprise the full text of the Eurocode including any annexes , as published by CEN, which may be preceded by a National title page and National foreword, and may be followed by a National annex.
The National annex may only contain information on those parameters which are left open in the Eurocode for national choice, known as Nationally Determined Parameters, to be used for the design of buildings and civil engineering works to be constructed in the country concerned, i. It may contain — decisions on the application of informative annexes, — references to non-contradictory complementary information to assist the user to apply the Eurocode. Furthermore, all the information accompanying the CE Marking of the construction products, which refer to Eurocodes, should clearly mention which Nationally Determined Parameters have been taken into account.
National annex for EN This standard gives alternative procedures, values and recommendations with notes indicating where national choices may have to be made. The National Standard implementing EN should have a National Annex containing all Nationally Determined Parameters for the design of steel structures to be constructed in the relevant country.
National choice is allowed in EN through clauses: — 2. However section 3 applies to steel grades S to S only. These normative references are cited at the appropriate places in the text and the publications are listed hereafter.
For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies including amendments. The following European Standards which are published or in preparation are cited in normative clauses: EN Welding. Steel product standards generally specify that test specimens should not fail at an impact energy lower than 27J at a specified test temperature T.
The temperature values T27J required in the product standards are located in the lower part of this region. It is not intended to cover the assessment of materials in service. The rules should be used to select a suitable grade of steel from the European Standards for steel products listed in EN NOTE For elements not subject to tension, welding or fatigue the rules can be conservative. In such cases evaluation using fracture mechanics may be appropriate, see 2.
Fracture toughness need not be specified for elements only in compression. Material of a less onerous grade shall not be used even though test results show compliance with the specified grade. To achieve realistic results, the models should be constructed and loaded in a similar way to the actual structure.
NOTE 1 The above combination is considered to be equivalent to an accidental combination, because of the assumption of simultaneous occurrence of lowest temperature, flaw size, location of flaw and material property. NOTE 2 In preparing the tabulated values in 2. This covers the dynamic action effects for most transient and persistent design situations.
The damage assumed is one quarter of the full fatigue damage obtained from EN Extrapolations beyond the extreme values are not valid. NOTE 3 Table 2. The flaw should meet the following requirements: — location and the shape should be appropriate for the notch case considered. The fatigue classification tables in EN may be used for guidance on appropriate crack positions. The assumed flaw should be located at the position of adverse stress concentration. The size of the initial crack should be chosen such that it represents the minimum value detectable by the inspection methods used in accordance with EN The crack growth from fatigue should be calculated with an appropriate fracture mechanics model using loads experienced during the design safe working life or an inspection interval as relevant.
Table 3. The use of class 1 is recommended. This strain arises from the shrinkage of the weld metal as it cools. It is greatly increased where free movement is restrained by other portions of the structure.
For example, at the point shown in Figure 3. Lamellar tearing is most likely to arise if the strain in the joint acts through the thickness of the material, which occurs if the fusion face is roughly parallel to the surface of the material and the induced shrinkage strain is perpendicular to the direction of rolling of the material.
