GSO EN 1998-6:2011 Scope
(1) The scope of Eurocode 8 is defined in EN 1998-1:2004, 1.1.1 and the scope of
this Standard is defined in (2) to (4). Additional parts of Eurocode 8 are indicated in EN
1998-1:2004, 1.1.3.
(2) EN 1998-6 establishes requirements, criteria, and rules for the design of tall
slender structures: towers, including bell-towers, intake towers, radio and TV-towers,
masts, chimneys (including free-standing industrial chimneys) and lighthouses.
Additional provisions specific to reinforced concrete and to steel chimneys are given in
Sections 5 and 6, respectively. Additional provisions specific to steel towers and to steel
guyed masts are given in Sections 7 and 8, respectively. Requirements are also given for
non-structural elements, such as antennae, the liner material of chimneys and other
equipment.
NOTE 1 Informative Annex A provides guidance and information for linear dynamic analysis
accounting for rotational components of the ground motion.
NOTE 2 Informative Annex B provides information and guidance on modal damping in modal
response spectrum analysis.
NOTE 3 Informative Annex C provides information on soil-structure interaction and guidance for
accounting for it in linear dynamic analysis.
NOTE 4 Informative Annex D provides supplementary information and guidance on the number of
degrees of freedom and the number of modes of vibration to be taken into account in the analysis.
NOTE 5 Informative Annex E gives information and guidance for the seismic design of Masonry
chimneys.
NOTE 6 Informative Annex F gives supplementary information for the seismic performance and
design of electrical transmission towers.
(3) The present provisions do not apply to cooling towers and offshore structures.
(4) For towers supporting tanks, EN 1998-4 applies.
