(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 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 should 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.
