BRITISH STANDARD BS EN 1993-3-22006 Eurocode 3 Design of steel structures Part 3-2 Towers, masts and chimneys Chimneys ICS 91.010.30; 91.060.40; 91.080.10 --,,,,,,,,,,,,--,,,,,,,--- BS EN 1993-3-22006 This British Standard was published under the authority of the Standards Policy and Strategy Committee on 30 May 2008 BSI 2008 ISBN 978 0 580 54894 9 National foreword This British Standard is the UK implementation of EN 1993-3-22006. 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 The conflicting national standards will be withdrawn at the end of the coexistence period, after all the EN Eurocodes of a package are available.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 allowed for national calibration during which the National Annex is issued, followed by a coexistence period of a maximum three years. During the coexistence period Member States are encouraged to adapt their national provisions. Conflicting national standards will be withdrawn by March 2010 at the latest. In the UK, the following national standard is partially superseded by BS EN 1993-3-22006. This standard will be withdrawn by March 2010 at the latest. Where a normative part of this EN allows for a choice to be made at the national level, the range and possible choice will be given in the normative text, and a note will qualify it as a Nationally Determined Parameter NDP. NDPs can be a specific value for a factor, a specific level or class, a particular or a particular application rule if several are proposed in the EN. To enable BS EN 1993-3-22006 to be used in the UK, the NDPs will be published in a National Annex, which will be made available by BSI in due course, after public consultation has taken place. The UK participation in its preparation was entrusted by Technical Committee B/525, Building and civil engineering structures, to Subcommittee B/525/32, Towers and masts and Subcommittee B/525/13, Chimneys. A list of organizations represented on this committee can be obtained on request to its secretary. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations.
