National foreword
This British Standard is the official English language version of
EN 1992-1-1:2004. It supersedes DD ENV 1992-1-1:1992,
DD ENV 1992-1-3:1996, DD ENV 1992-1-4:1996, DD ENV 1992-1-5:1996,
DD ENV 1992-1-6:1996 which will be withdrawn.
The structural Eurocodes are divided into packages by grouping Eurocodes for
each of the main materials, concrete, steel, composite concrete 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 The conflicting national standards will be withdrawn at the end of the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 available.
Following publication of the EN, there is a period of 2 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 provisions to
withdraw conflicting national rules before the end of the coexistent 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(s) will be
withdrawn.
In the UK, the corresponding national standards are:
- BS 8110-1:1997, Structural use ofconcrete - Part 1: Code ofpractice for
design and construction;
_
BS 8110-2:1985, Structural use of concrete -- Part 2: Code ofpractice for
special circumstances;
BS 8110-3:1985, Structural use of concrete - Part 3: Design charts for
_
singly reinforced beams, doubly reinforced beams and rectangular columns;
and based on this transition period, these standards will be withdrawn on a
date to be announced.
