This British Standard is the official English language version of EN 1998-5:2004. It supersedes DD ENV 1998-5:1996 which is withdrawn.
(1)P This Part of Eurocode 8 establishes the requirements, criteria, and rules for the siting and foundation soil of structures for earthquake resistance. It covers the design of different foundation systems, the design of earth retaining structures and soil-structure interaction under seismic actions. As such it complements Eurocode 7 which does not cover the special requirements of seismic design.
(2)P The provisions of Part 5 apply to buildings (EN 1998-1), bridges (EN 1998-2),
towers, masts and chimneys (EN 1998-6), silos, tanks and pipelines (EN 1998-4).
(3)P Specialised design requirements for the foundations of certain types of structures, when necessary, shall be found in the relevant Parts of Eurocode 8.
(4) Annex B of this Eurocode provides empirical charts for simplified evaluation of liquefaction potential, while Annex E gives a simplified procedure for seismic analysis of retaining structures.
