Introduction The Eurocodefamily
The introduction of Europeanstandardsto UK
construction isa significant event.Theten design
standards,known asthe Eurocodes,will affect
all designand construction activities as current
British standardsfor designare due to be
withdrawn in 2010.
This guide shows how to use Eurocode21with the other Eurocodes.In
particular it introduces Eurocode:Basisof structuraldesign2and Eurocode1:
Actionson structures3and guides the designerthrough the processof
determining the designvaluesfor actions on a structure. It alsogivesa brief
overview of the significant differencesbetween the Eurocodesand BS81104,
(which will be superseded)and includesa glossaryof Eurocodeterminology.
This publication is part of the seriesof guides
entitled How to designconcretestructuresusing
Eurocode2.Their aim isto makethe transition to

aspossibleby drawing together in one place key
information and commentary requiredfor the
designof typical concrete elements.
The development of the Eurocodesstarted in 1975; sincethen they have
evolved significantly and are now claimed to be the most technically
advancedstructural codesin the world.Themany benefits of usingEurocode2
are summarisedbelow.Thereareten Eurocodescoveringall the main structural
materials (seeFigure1).Theyare produced by the EuropeanCommittee for
Standardization(CEN),and will replaceexisting national standardsin 28
countries.
Thecement and concrete industry recognisedthat
a substantial effort wasrequiredto ensurethat
the UKdesignprofessionwould beable to use
Eurocode2 quickly,effectively,efficiently andwith
confidence.With support from government.
consultantsand relevant industry bodies,the
Concrete Industry Eurocode2 Group (CIEG)was
formed in 1999 and this Group has providedthe
guidancefor a co-ordinated and collaborative
approachto the introduction of Eurocode2.As
a result, a rangeof resourcesis to bemade
availablethrough TheConcreteCentre to help
designersduring the transition period (seeback
cover for details).
Eachcountry isrequired to publish a Eurocodewith a national title pageand
forward but the original text of the Eurocodemust appearas producedby
CENasthe main body of the document. A National Annex (NA) can be
included at the backof the document (seeFigure2). All the guidesin this
seriesassumethat the UKNational Annexeswill be used.
Table 1 details which existing standards relating to concrete designwill be
replacedby the new Eurocodes.During the implementation period it is
recommended that existing standardsareconsidered for usewhere the
Europeanstandards have not yet been issued.

Benefits of using Eurocode 2
Learning to use the new Eurocodeswil l require t ime and effort on
behalf of the designer, so what benefits will there be?
1. The new Eurocodesare claimed to be the most technically
advanced codes in the world.2. Eurocode2 should result in more economic structures than
BS8110.
3. The Eurocodes are logical and organised to avoid repetition.
4. Eurocode 2 is less restrictive than existing codes.
5. Eurocode 2 is more extensive than existing codes.
6. Useof the Eurocodeswil l provide more opportunity for designers
to work throughout Europe.
7. In Europeall public works must allow the Eurocodesto be used.
