(1)The scope of Eurocode 8 is defined in EN 1998-1:2004, andThe scope of this standard is defined in (2), (4) and (5). Additional parts of Eurocode 8 are indicated in EN 1998-1:2004, . (2)The scope of EN 1998-3 is as follows:To provide criteria forThe evaluation of the seismic performance of existing individual building structures; To describeThe approach in selecting necessary corrective measures; To set forth criteria forThe design of retrofitting measures (i.e. conception, structural analysis including intervention measures, final dimensioning of structural parts andTheir connections to existing structural elements). NOTE ForThe purposes of this standard, retrofitting covers bothThe strengthening of undamaged structures andThe repair of earthquake damaged structures. (3) When designing a structural intervention to provide adequate resistance against seismic actions, structural verifications should also be made with respect to non-seismic load combinations. (4) ReflectingThe basic requirements of EN 1998-1:2004,This standard coversThe seismic assessment and retrofitting of buildings made of the more commonly used structural materials:concrete, steel, and masonry. NOTE Informative Annexes A, B and C contain additional information related toThe assessment of reinforced concrete, steel and composite, and masonry buildings, respectively, and toTheir upgrading when necessary. (5) AlthoughThe provisions of this standard are applicable to all categories of buildings,The seismic assessment and retrofitting of monuments and historical buildings often requires different types of provisions and approaches, depending onThe nature of the monuments. (6) Since existing structures:(i) reflectThe state of knowledge atThe time of their construction, (ii) possibly contain hidden gross errors, (iii) may have been submitted to previous earthquakes or other accidental actions with unknown effects, structural evaluation and possible structural intervention are typically subjected to a different degree of uncertainty (level of knowledge) thanThe design of new structures. Different sets of material and structural safety factors areTherefore required, as well as different analysis procedures, depending onThe completeness and reliability of the information available.

1 Scope of EN 1998 (1)P EN 1998 applies to the design and construction of buildings and civil engineering works in seismic regions. Its purpose is to ensure that in the event of earthquakes: - human lives are protected; - damage is limited; and - structures important for civil protection remain operational. NOTE The random nature of the seismic events and the limited resources available to counter their effects are such as to make the attainment of these goals only partially possible and only measurable in probabilistic terms. The extent of the protection that can be provided to different categories of buildings, which is only measurable in probabilistic terms, is a matter of optimal allocation of resources and is therefore expected to vary from country to country, depending on the relative importance of the seismic risk with respect to risks of other origin and on the global economic resources. (2)P Special structures, such as nuclear power plants, offshore structures and large dams, are beyond the scope of EN 1998. (3)P EN 1998 contains only those provisions that, in addition to the provisions of the other relevant Eurocodes, must be observed for the design of structures in seismic regions. It complements in this respect the other Eurocodes. (4)EN 1998 is subdivided into various separate Parts (see 1.1.2 and 1.1.3). 2 Scope of EN 1998-1 (1) EN 1998-1 applies to the design of buildings and civil engineering works in seismic regions. It is subdivided in 10 Sections, some of which are specifically devoted to the design of buildings. (2) Section 2 of EN 1998-1 contains the basic performance requirements and compliance criteria applicable to buildings and civil engineering works in seismic regions. (3) Section 3 of EN 1998-1 gives the rules for the representation of seismic actions and for their combination with other actions. Certain types of structures, dealt with in EN 1998-2 to EN 1998-6, need complementing rules which are given in those Parts. (4) Section 4 of EN 1998-1 contains general design rules relevant specifically to buildings. (5) Sections 5 to 9 of EN 1998-1 contain specific rules for various structural materials and elements, relevant specifically to buildings as follows: - Section 5: Specific rules for concrete buildings; - Section 6: Specific rules for steel buildings; - Section 7: Specific rules for composite steel-concrete buildings; - Section 8: Specific rules for timber buildings; - Section 9: Specific rules for masonry buildings. (6) Section 10 contains the fundamental requirements and other relevant aspects of design and safety related to base isolation of structures and specifically to base isolation of buildings. NOTE Specific rules for isolation of bridges are developed in EN 1998-2. (7) Annex C contains additional elements related to the design of slab reinforcement in steel-concrete composite beams at beam-column joints of moment frames. NOTE Informative Annex A and informative Annex B contain additional elements related to the elastic displacement response spectrum and to target displacement for pushover analysis. 3 Further Parts of EN 1998 (1)P Further Parts of EN 1998 include, in addition to EN 1998-1, the following: - EN 1998-2 contains specific provisions relevant to bridges; - EN 1998-3 contains provisions for the seismic assessment and retrofitting of existing buildings; - EN 1998-4 contains specific provisions relevant to silos, tanks and pipelines; - EN 1998-5 contains specific provisions relevant to foundations, retaining structures and geotechnical aspects; - EN 1998-6 contains specific provisions relevant to towers, masts and chimneys.

(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. NOTE 1 Informative Annex A provides information on topographic amplification factors. NOTE 2 Informative Annex C provides information on the static stiffness of piles. NOTE 3 Informative Annex D provides information on dynamic soil-structure interaction. NOTE 4 Informative Annex F provides information on the seismic bearing capacity of shallow foundations.

(1) This standard deals with the planning, structural design and detailing of conventional buildings made from reinforced concrete, steel, timber or masonry in German earthquake zones. The purpose of the standard is to save human lives, to limit damage and to ensure that structures of importance for public safety as well as infrastructure remain in working order in the event of an earthquake. (2) This standard does not apply to structures and parts of such (e.g. nuclear power plants, chemical plants etc.) which may present additional potential hazards in the event of an earthquake. (3) This standard does not generally substitute the general rules to be observed when designing and planning structures, but provides supplementary rules that are applicable in earthquake zones. (4) Those parts of Germany which, within the scope of this standard, are more liable to be affected by earthquakes are grouped into earthquake zones 1 to 3 (see Figure 2). The extent of hazards due to earthquakes (seismicity) in areas outside of earthquake zones 1 to 3 can be assumed to be so Iow that this standard need not be applied in such areas.

Linear accelerators and targets are considered nonreactor nuclear facilities. Incidental use and generation of radioactive materials in a facility operation (e&, check and calibration sources and use of radioactive sources in research, experimental, and analytical laboratory activities, electron microscopes, and X-ray machines) would not ordinarily require the facility to be included in this definition.
