3、ritish Standard is the official English language version of EN 1996-1-1:2005. It supersedes DD ENV 1996-1-1:1996 and DD ENV 1996-1-3:2001 which are withdrawn. The structural Eurocodes are divided into packages by grouping Eurocodes for each of the main materials, concrete, steel, composite concrete
4、and steel, timber, masonry and aluminium. This is to enable a common date of withdrawal (DOW) for all the relevant parts that are needed for a particular design. The conflicting national standards will be withdrawn at the end of the coexistence period, after all the EN Eurocodes of a package are ava
5、ilable. Following publication of the EN, there is a period of two years allowed for the national calibration period during which the national annex is issued, followed by a three year coexistence period. During the coexistence period Member States will be encouraged to adapt their national provision
6、s to withdraw conflicting national rules before the end of the coexistence period. The Commission in consultation with Member States is expected to agree the end of the coexistence period for each package of Eurocodes. At the end of this coexistence period, the national standard will be withdrawn. I
