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withdrawn in 2010.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(which will be superseded)and includesa glossaryof Eurocodeterminology.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

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.
