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 encoura

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 na

49、of an identical text or by endorsement, at the latest by March 2004, andconflicting national standards shall be withdrawn at the latest by 20 .This document supersedes ENV 1991-3:1995.CEN/TC 250 is responsible for all Structural Eurocodes.Background of the Eurocode ProgrammeIn 1975, the Commission of the European Community decided on an action programmein the field of construction, based on article 95 of the Treaty. The objective of theprogramme was the elimination of technical obstacles to trade and the harmonisation oftechnical specifications.Within this action programme,
