This British Standard is the official English language version of
EN 1994-2:2005. It supersedes DD ENV 1994-2:2001 which is withdrawn.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 The conflicting national standards will be withdrawn at the end of the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 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 provisions 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At the end of this coexistence period, the national standard will be withdrawn.
In the UK, the corresponding national standard is:
- BS 5400-5:1979, Steel, concrete and composite bridges- Code of practice
for design of composite bridges
and based on this transition period this standard will be withdrawn on a date
to be announced.
The UK participation in its preparation was entrusted by Technical Committee
B/525, Building and civil engineering structures, to Subcommittee B/525/4,
Composite structures, which has the responsibility to:
aid enquirers to understand the text;
present to the responsible international/European committee any
enquiries on the interpretation, or proposals for change, and keep UK
intere sts informed;
monitor related international and European developments and
promulgate them in the UK.
A list of organizations represented on this subcommittee can be obtained on
request to its secretary.
