0 Introduction
0.1 Introduction to the Eurocodes
The Structural Eurocodes comprise the following standards generally consisting of a number of Parts:
— EN 1990 Eurocode: Basis of structural and geotechnical design
— EN 1991 Eurocode 1: Actions on structures
— EN 1992 Eurocode 2: Design of concrete structures
— EN 1993 Eurocode 3: Design of steel structures
— 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
The Eurocodes are intended for use by designers, clients, manufacturers, constructors, relevant
authorities (in exercising their duties in accordance with national or international regulations),
educators, soft-ware developers, and committees drafting standards for related product, testing and
execution standards.
NOTE Some aspects of design are most appropriately specified by relevant authorities or, where not specified,
can be agreed on a project-specific basis between relevant parties such as designers and clients. The Eurocodes
identify such aspects making explicit reference to relevant authorities and relevant parties.
0.2 Introduction to EN 1996 Eurocode 6
EN 1996 Eurocode 6 standards apply to the design of building and civil engineering works, or parts
thereof, in unreinforced, reinforced, prestressed and confined masonry.
EN 1996 (all parts) deal only with the requirements for resistance, serviceability and durability of
structures. Other requirements, for example, concerning thermal or sound insulation, are not considered.
EN 1996 (all parts) do not cover the specific requirements of seismic design. Provisions related to such
requirements are given in EN 1998 (all parts), which complements, and is consistent with EN 1996 (all
parts).
EN 1996 (all parts) do not cover numerical values of the actions on building and civil engineering works
to be taken into account in the design. They are provided in EN 1991(all parts).
0.3 Introduction to EN 1996-1-1
For the design of new structures, EN 1996-1-1 is intended to be used, for direct application, together with
the other Eurocodes where applicable.

0.4 Verbal forms used in the Eurocodes
The verb “shall" expresses a requirement strictly to be followed and from which no deviation is permitted
in order to comply with the Eurocodes.
The verb “should” expresses a highly recommended choice or course of action. Subject to national
regulation and/or any relevant contractual provisions, alternative approaches could be used/adopted
where technically justified.
The verb “may" expresses a course of action permissible within the limits of the Eurocodes.
The verb “can" expresses possibility and capability; it is used for statements of fact and clarification of
concepts.
0.5 National Annex for EN 1996-1-1
National choice is allowed in this standard where explicitly stated within notes. National choice includes
the selection of values for Nationally Determined Parameters (NDPs).
The national standard implementing EN 1996-1-1 can have a National Annex containing all national
choices to be used for the design of buildings and civil engineering works to be constructed in the relevant
country.
When no national choice is given, the default choice given in this standard is to be used.
When no national choice is made and no default is given in this standard, the choice can be specified by a
relevant authority or, where not specified, agreed for a specific project by appropriate parties.
National choice is allowed in EN 1996-1-1 through notes to the following:
4.4.4(2) 5.2.2(2) 5.7.1.2(1) 5.7.1.3(2)
5.7.2.1(1) 5.7.2.1(2) 5.7.2.2(4) 5.7.4(4) – 3 choices
5.8.2(3) 5.8.4(3) 6.3.3(2) 6.3.3(3)
7.5.1.4(4) 8.3.1(2) 8.10.3.1(2) 10.1.2(2)
10.5.2.2(2) 10.5.2.3(2) 10.6.2(1) 10.6.3(1)
National choice is allowed in EN 1996-1-1 on the application of the following informative annexes:
Annex A Annex B Annex C Annex D
Annex E Annex F Annex G Annex H
Annex I Annex J Annex K
The National Annex can contain, directly or by reference, non-contradictory complementary information
for ease of implementation, provided it does not alter any provisions of the Eurocodes.
