Eurocode 3 - Bemessung und Konstruktion von Stahlbauten - Teil 3-2: Türme, Maste und Schornsteine - Schornsteine

1.1   Anwendungsbereich
(1)   EN 1993-3-2 behandelt die Bemessung und Konstruktion vertikaler Stahlschorn¬steine mit zylindrischer oder konischer Form. Sie schließt Schornsteine ein, die als Kragsystem ausgebildet oder auf unterschied¬lichen Ebenen abgestützt oder abgespannt sind.
(2)   Die Regeln in diesem Teil ergänzen die Regeln von EN 1993-1-1.
(3)   Der Teil 3-2 befasst sich nur mit den Belangen der Beanspruchbarkeit (Festigkeit, Stabilität, Ermüdung) von Stahlschornsteinen.
ANMERKUNG In diesem Zusammenhang (Beanspruchbarkeit) bezieht sich der Begriff Schornstein auf:
a)   Schornsteinkonstruktionen;
b)   die zylindrischen Stahlbauteile von Türmen;
c)   den zylindrischen Stahlschaft abgespannter Maste.
(4)   Chemische Beanspruchung, thermodynami¬sches Verhalten und Wärmedämmung sind in EN 13084-1 geregelt, Bemessung und Konstruktion von Innenrohren in EN 13084-6.

Foreword
This European Standard 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 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text or by endorsement, at the latest by April 2007 and conflicting National Standards shall be withdrawn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 Regulations, 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,

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 Standard 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)

1 General
1.1 Scope
(1) This Part 3.2 of EN 1993 applies to the structural design of vertical steel chimneys of circular or
conical 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.
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 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 annex 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 1
