What is BS EN 1998-6 - Earthquake resistance of towers, masts, and chimneys about?
BS EN 1998-6 is the sixth part of the BS EN 1998 multi-series that discusses the design of structures for earthquake resistance.
BS 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. Requirements are also given for non-structural elements, such as antennae, the liner material of chimneys and other equipment.
Who is BS EN 1998-6 - Earthquake resistance of towers, masts, and chimneys for?
BS EN 1998-6 on the design of towers, masts and chimneys for earthquake resistance is useful for:
- Civil engineers
- Regulatory authorities
- Manufacturers or suppliers of concrete structures
Why should you use BS EN 1998-6 - Earthquake resistance of towers, masts, and chimneys?
Towers, masts and chimneys are vertical structures with a low centre of gravity and are highly prone to collapse in the event of an earthquake. Hence, these structures need to be constructed bearing with high resistance to earthquakes.
BS EN 1998-6 includes the additional criteria and rules required for the seismic design of these structures without restrictions on their size, structural types and other functional characteristics., BS EN 1998-6 also provides detailed methods of assessment and verification rules.
Overall, the guidelines of BS EN 1998-6 help you to design towers, masts and chimneys that have a higher earthquake resistance.
Second Generation of EN Eurocode Standards
The second generation of EN Eurocode standards is expected to be published between 2023 and 2026. These documents are being published as soon as they are available, to enable users to prepare for the transition from the first generation to second generation of Eurocodes. As set out in the National foreword of the BS EN second generation Eurocodes, UK adoptions of the first generation of Eurocodes will be withdrawn by BSI on 30 March 2028. That means there is a period of coexistence between 2023 and 2028 during which both first and second generation Eurocodes are available.
Until 30 March 2028, the first generation documents should be considered as the applicable standards for buildings and civil engineering works constructed in the UK unless otherwise specified by the relevant authority or in the specification for a particular project. While the use of provisions in second generation Eurocodes in conjunction with first generation Eurocodes is not precluded, it should be undertaken with care and should only be done when users are satisfied that it will not result in a lower level of reliability than the minimum level set in the first generation Eurocodes and associated UK National Annexes.
