3. National Foreword
NSAI adopts all Eurocodes as Irish Standards.
Eurocodes permit certain design parameters to be selected nationally. In Ireland, the selection
of National Design Parameters (NDP's) is the responsibility of the Eurocodes Consultative
Committee (NSAI TC 015). National Annexes are developed in accordance with CEN and NSAI
procedures and include a public consultation process.
Where NSAI TC 015 considers it appropriate, NDP's are agreed and listed in Irish National
Annexes to Eurocodes.
Eurocodes must always be used in conjunction with the accompanying National Annex (NA),
where available. For example, I.S. EN 1991-1-4, Eurocode 1: Actions on structures – Part 1-4:
General actions – Wind actions is to be used in conjunction with NA to I.S. EN 1991-1-4.
National Annexes are reviewed as necessary e.g. when a new edition, an amendment or a
corrigendum to a Eurocode is issued. The National Annex identifies what
amendments/corrigenda are addressed. The user should check that the National Annex
addresses the latest changes to the Eurocode. Previews of all documents are available on
www.standards.ie. Any questions should be directed to NSAI.
Where an Irish National Annex to a Eurocode has not been prepared, the user must make sure
that the general requirements of I.S. EN 1990 and the accompanying Irish National Annex are
complied with.
Where a Eurocode has been changed (revised/amended/corrected) and the National Annex has
yet to be revised to account for the change(s), the National Annex for the previous version is
available. Engineering judgement must be applied if using guidance contained therein e.g. when
selecting appropriate parameters.
Information on Eurocodes and the related national annexes is available from www.nsai.ie.
In Line with international standards practice the decimal point is shown as a comma (,)
throughout this document.

Foreword
This document (EN 1997-1) has been prepared by Technical Committee CEN/TC250
“Structural Eurocodes”, the secretariat of which is held by BSI. CEN/TC 250 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 May 2005 and conflicting national
standards shall be withdrawn by March 2010.
This document supersedes ENV 1997-1:1994.
According to the CEN/CENELEC Internal Regulations, the national standards 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, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
Background to the Eurocode programme
In 1975, 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 harmonisation of technical specifications.
Within this action programme, the Commission took the initiative to establish a set of
harmonised 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 1980s.
In 1989, the Commission and the Member States of the EU and EFTA decided, on the basis of
an agreement1
between the Commission and CEN, to transfer the preparation and the
publication of the Eurocodes to CEN through a series of Mandates, in order to provide them
with a future status of European Standard (EN). This links de facto the Eurocodes with the
provisions of all the Council’s Directives and/or Commissions Decisions dealing with European
standards (e.g. the Council Directive 89/106/EEC on construction products - CPD - and
Council Directives 93/37/EEC, 92/50/EEC and 89/440/EEC on public works and services and
equivalent EFTA Directives initiated in pursuit of setting up the internal market).
The Structural Eurocode programme comprises the following standards generally consisting of
a number of Parts:
EN 1990 Eurocode : Basis of Structural Design
EN 1991 Eurocode 1: Actions on structures
EN 1992 Eurocode 2: Design of concrete structures
EN 1993 Eurocode 3: Design of steel structures
1 Agreement between the Commission of the European Communities and the European Committee for
Standardisation (CEN) concerning the work on EUROCODES for the design of building and civil engineering works
(BC/CEN/03/89).

EN 1994 Eurocode 4: Design of composite steel and concrete structures
EN 1995 Eurocode 5: Design of timber structures
EN 1996 Eurocode 6: Design of masonry structures
EN 1997 Eurocode 7: Geotechnical design
EN 1998 Eurocode 8: Design of structures for earthquake resistance
EN 1999 Eurocode 9: Design of aluminium structures
Eurocode standards recognise the responsibility of regulatory authorities in each Member
State and have safeguarded their right to determine values related to regulatory safety matters
at national level where these continue to vary from State to State.
Status and field of application of Eurocodes
The Member States of the EU and EFTA recognise that Eurocodes serve as reference
documents for the following purposes:
— as a means to prove compliance of building and civil engineering works with the essential
requirements of Council Directive 89/106/EEC, particularly Essential Requirement N°1 –
Mechanical resistance and stability – and Essential Requirement N°2 – Safety in case of
fire;
— as a basis for specifying contracts for construction works and related engineering services;
— as a framework for drawing up harmonised technical specifications for construction
products (ENs and ETAs)
The Eurocodes, as far as they concern the construction works themselves, have a direct
relationship with the Interpretative Documents2
referred to in Article 12 of the CPD, although
they are of a different nature from harmonised product standards3
. Therefore, technical aspects
arising from the Eurocodes work need to be adequately considered by CEN Technical
Committees and/or EOTA Working Groups working on product standards with a view to
achieving full compatibility of these technical specifications with the Eurocodes.
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.
2 According to Art. 3.3 of the CPD, the essential requirements (ERs) shall be given concrete form in interpretative
documents for the creation of the necessary links between the essential requirements and the mandates for
harmonised ENs and ETAGs/ETAs.
3 According to Art. 12 of the CPD the interpretative documents shall :
a) give concrete form to the essential requirements by harmonising the terminology and the technical bases and indicating
classes or levels for each requirement where necessary ;
b) indicate methods of correlating these classes or levels of requirement with the technical specifications, e.g. methods of
calculation and of proof, technical rules for project design, etc. ;
c) serve as a reference for the establishment of harmonised standards and guidelines for European technical approvals.
The Eurocodes, de facto, play a similar role in the field of the ER 1 and a part of ER 2.

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.e. :
— values and/or classes where alternatives are given in the Eurocode,
— values to be used where a symbol only is given in the Eurocode,
— country specific data (geographical, climatic), e.g. snow map,
— the procedure to be used where alternative procedures are given in the Eurocode.
It may also contain:
— decisions on the application of informative annexes,
— references to non-contradictory complementary information to assist the user to apply the
Eurocode.
Links between Eurocodes and harmonised technical specifications (ENs and ETAs) for
products
There is a need for consistency between the harmonised technical specifications for
construction products and the technical rules for works4
. 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.
Additional information specific to Eurocode 7
EN 1997-1 gives design guidance and actions for geotechnical design of buildings and civil
engineering works.
EN 1997-1 is intended for clients, designers, contractors and public authorities.
EN 1997-1 is intended to be used with EN 1990 and EN 1991 to EN 1999.
In using EN 1997-1 in practice, particular regard should be paid to the underlying assumptions
and conditions given in 1.3.
The 12 sections of EN 1997-1 are complemented by 1 normative and 8 informative annexes.
National annex for EN 1997-1
This standard gives alternative procedures and recommended values with notes indicating
where national choices may have to be made. Therefore the National Standard implementing
EN 1997-1 should have a National annex containing all Nationally Determined Parameters to
be used for the design of buildings and civil engineering works to be constructed in the relevant
country.

Section 1 General
1.1 Scope
1.1.1 Scope of EN 1997
(1) EN 1997 is intended to be used in conjunction with EN 1990:2002, which establishes the
principles and requirements for safety and serviceability, describes the basis of design and
verification and gives guidelines for related aspects of structural reliability.
(2) EN 1997 is intended to be applied to the geotechnical aspects of the design of buildings
and civil engineering works. It is subdivided into various separate parts (see 1.1.2 and 1.1.3).
(3) EN 1997 is concerned with the requirements for strength, stability, serviceability and
durability of structures. Other requirements, e.g. concerning thermal or sound insulation, are
not considered.
(4) Numerical values of actions on buildings and civil engineering works to be taken into
account in design are provided in EN 1991 for the various types of construction. Actions
imposed by the ground, such as earth pressures, shall be calculated according to the rules of
EN 1997.
(5) Separate European Standards are intended to be used to treat matters of execution and
workmanship. They are denoted in the relevant sections.
(6) In EN 1997 execution is covered to the extent that is necessary to comply with the
assumptions of the design rules.
(7) EN 1997 does not cover the special requirements of seismic design. EN 1998 provides
additional rules for geotechnical seismic design, which complete or adapt the rules of this
Standard.
1.1.2 Scope of EN 1997-1
(1) EN 1997-1 is intended to be used as a general basis for the geotechnical aspects of the
design of buildings and civil engineering works.
(2) The following subjects are dealt with in EN 1997-1:
Section 1: General
Section 2: Basis of geotechnical design
Section 3: Geotechnical data
Section 4: Supervision of construction, monitoring and maintenance
Section 5: Fill, dewatering, ground improvement and reinforcement
Section 6: Spread foundations
Section 7: Pile foundations
Section 8: Anchorages
Section 9: Retaining structures

(3) EN 1997-1 is accompanied by Annexes A to J, which provide:
— in A: recommended partial safety factor values; different values of the partial factors may be
set by the National annex;
— in B to J: supplementary informative guidance such as internationally applied calculation
methods.
1.1.3 Further Parts of EN 1997
(1) EN 1997-1 is supplemented by EN 1997-2 that provides requirements for the performance
and evaluation of field and laboratory testing.
1.2 Normative references
