National foreword This standard has been prepared by Technical Committee CEN/TC 250 “Structural Eurocodes” (Secretari
5、at: BSI, United Kingdom). The responsible German body involved in its preparation was the Normenausschuss Bauwesen (Building and Civil Engineering Standards Committee), Working Committee NA 005-11-37 AA Industrieschornsteine.

24、rd EN 1993-3-2, Eurocode 3: Design of steel structures: Part 3-2 Towers, masts and chimneys Chimneys, has been prepared by Technical Committee CEN/TC250 Structural Eurocodes , the Secretariat of which is held by BSI. CEN/TC250 is responsible for all Structural Eurocodes. This European Standard shall
25、 be given the status of a National Standard, either by publication of an identical text or by endorsement, at the latest by April 2007 and conflicting National Standards shall be withdrawn at latest by March 2010. This Eurocode supersedes ENV 1993-3-2. According to the CEN-CENELEC Internal Regulatio
26、ns, the National Standard Organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
27、 Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. National Annex for EN 1993-3-2 This standard gives alternative procedures, values and recommendations for classes with notes indicating where national choices may have to be made. Therefore the National St
28、andard implementing EN 1993-3-2 should have a National Annex containing all Nationally Determined Parameters to be used for the design of steel structures to be constructed in the relevant country. National choice is allowed in EN 1993-3-2 through paragraphs: 2.3.3.1(1) 2.3.3.5(1) 2.6(1) 4.2(1) 5.1(

30、l section. It covers chimneys that are cantilevered, supported at intermediate levels or guyed. (2) The provisions in this Part supplement those given in Part 1.1 of EN 1993. (3) This Part 3.2 is concerned only with the requirement for resistance (strength, stability and fatigue) of steel chimneys.
31、NOTE: In this context (i.e. resistance) the term chimney refers to: a) chimney structures b) the steel cylindrical elements of towers c) the steel cylindrical shafts of guyed masts (4) For provisions concerning aspects, such as chemical attack, thermo-dynamical performance or thermal insulation see
32、EN 13084-1. For the design of liners see EN 13084-6. (5) Foundations in reinforced concrete for steel chimneys are covered in EN 1992 and EN 1997. See also 4.7 and 5.4 of EN 13084-1. (6) Wind loads are specified in EN 1991-1-4. NOTE: Procedures for the wind response of guyed chimneys are given in an
33、nex B of EN 1993-3-1. (7) This Part does not cover special provisions for seismic design, which are given in EN 1998-6. See also 5.2.4.1 of EN 13084-1. (8) Provisions for the guys and their attachments are given in EN 1993-3-1 and EN 1993-1-11. (9) For the execution of steel chimneys, reference shou
34、ld be made to EN 1090, Part 2 and EN 13084-1. NOTE: Execution is covered to the extent that is necessary to indicate the quality of the construction materials and products that should be used and the standard of workmanship on site needed to comply with the assumptions of the design rules.

35、following subjects are dealt with in EN 1993-3-2: Section 1: General Section 2: Basis of design Section 3: Materials Section 4: Durability Section 5: Structural analysis Section 6: Ultimate limit states Section 7: Serviceability limit states Section 8: Design assisted by testing Section 9: Fatigue D
