National foreword

This Draft for Development is the official English version of ENV 1999-2:1998.

This publication is not to be regarded as a British Standard.

It is being issued in the Draft for Development series of publications and is of a provisional nature. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained.

Comments arising from the use of this Draft for Development are requested so that UK experience can be reported to the European organization responsible for its conversion into a European Standard. A review of this publication will be initiated 2 years after its publication by the European organization so that a decision can be taken on its status at the end of its three-year life. The commencement of the review period will be notified by an announcement in Update Standards.

According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to support the conversion into a European standard, to extend the life of the prestandard or to withdraw it. Comments should be sent in writing to the Secretary of BSI Subcommittee B/525/9, Structural use of aluminium, at 389 Chiswick High Road, London W4 4AL, giving the document reference and clause number and proposing, where possible, an appropriate revision of the text.

A list of organizations represented on this committee can be obtained on request to its secretary.

National Application Document Introduction

This National Application Document (NAD) has been prepared under the direction of Technical Committee B525, Building & Civil Engineering structures, (by subcommittee B525/9). It has been developed from:

a) a textural examination of ENV 1999-2:1998;

b) a parametric calibration against BS8118, supporting standards and test data;

c) trial calculations

1 Scope

This NAD provides information to enable ENV 1999-2:1998 (Eurocode 9 Part 2) to be used for the design of buildings and civil and structural engineering works in the UK or parts thereofwhich are susceptible to fatigue.

2 References

2.1 Normative References

This NAD incorporates, by reference, provisions from specific editions of other publications. These normative references are cited at the appropriate points in the text. Subsequent amendments to, or revision of, any of these publications apply to this NAD only when incorporated in it by updating or revision.

2.2 Informative References

This NAD refers to other publications that provide information or guidance. Editions of these publications current at the time of issue of this standard are listed, but reference should be made to the latest editions.

3 Partial safety factors, combination factors and other values a) The values for partial load factors (y) should be those given in DD ENV 1999- 2: 1998 Clause 3.4

b) The values for partial safety factors (ym) should be those given in ENV 1999-2: 1998 Clause 5.2.1(3). [see also 6.1.1 d) belowre. ym for adhesivelybondedjoints].

4 Loading Codes

Guidance on loading specifically for fatigue may be obtained from:

Rules for the design of cranes

Part 1: "Specification for classification, stress calculations and design criteria for structures"

BS2573 Part 2: 1980

Rules for the design of cranes

Part 2: "Specification for classification, stress calculations and design ofmechanisms"

5 Reference Standards

The supporting standards to be used are listed in Tables 2 to 11.

6 Additional Recommendations 6.1 Guidance on Eurocode 9 : Part 1.1

Note. 6.1.1 to 6.1.5 should be followed when designing in accordance with Eurocode 9: Part 2

6.1.1 Chapter 1 General a) Clause 1.1.1(2) Damage tolerance

The use ofdamage tolerant designs [refEurocode 9: Part 2 clauses 2.1.6(2) and 2.3.1] should be limited to any structural applications that would normally be subjected to regular inspections for fatigue damage.

b) Clause1.1.3 products

Designers wishing to employ castings under fatigue conditions should consult the manufacturers and consider prototype fatigue testing ofcomponents.

c) Clause1.1.5

Range ofmaterials. Use ofaluminium alloy products listed in the British Standards given in Table 1 is also permitted.

NOTE: This provision is to enable the use of materials held in stock which were produced prior to the adoption of the EN material standards.

d) Clause 1.1.6Joining Methods

Whilst adhesive bonding is listed in this clause, they should not be used under fatigue conditions without consultation with the manufacturers and representative testing ofa sufficient number ofsamples.

6.1.2 Section2BasisofDesign a) Clause 2.1.6(2) Damage tolerant design - see notes above re Clause 1.1.1.

b) Clause 3 - Damage tolerant design - see notes above re Clause 1.1.1.

6.1.3 Section 3 - Loading a) Clause 3.1(2) Delete reference to ENV 1991 and use loading codes relevant to particular application (see also section 4 above) or actual data as available.

6.1.4 Section 4 - Loading a) Clause 4.2.2(1)e) Delete "(see Part 1 ofthis Prestandard)" and replace with "In a web in shear the modified nominal stress should be calculated using an effective thickness of 1.7pvtw (but not more than tw). The value of pv should be taken from clause 5.12.4 and 5.12.5 ofDD ENV 1999-1-1."

6.1.5 Section 5 Fatigue Strength Data a) Clause 5.2.3 (3)

Adhesive bonding should not be used in fatigue conditions without representative test data. (See refto Clause 1.1.6 above). Delete the sentence "otherwise a high value of ymf should be used".

The fatigue curve and detail category should only be used for non-critical applications or for preliminary design prior to representative testing.
