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.

(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), (4) and (5). Additional parts of Eurocode 8 are indicated in EN 1998-1: 2004, 1.1.3. (2) The scope of EN 1998-3 is as follows: − To provide criteria for the evaluation of the seismic performance of existing individual building structures. − To describe the approach in selecting necessary corrective measures − To set forth criteria for the design of retrofitting measures (i.e. conception, structural analysis including intervention measures, final dimensioning of structural parts and their connections to existing structural elements). NOTE For the purposes of this standard, retrofitting covers both the strengthening of undamaged structures and the 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) Reflecting the basic requirements of EN 1998-1: 2004, this Standard covers the 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 to the assessment of reinforced concrete, steel and composite, and masonry buildings, respectively, and to their upgrading when necessary. (5) Although the 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 on the nature of the monuments. (6) Since existing structures: (i) reflect the state of knowledge at the 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) than the design of new structures. Different sets of material and structural safety factors are therefore required, as well as different analysis procedures, depending on the completeness and reliability of the information available.

(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.

(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 this clause. Additional parts of Eurocode 8 are indicated in EN 1998-1: 2004, 1.1.3. (2) This standard specifies principles and application rules for the seismic design of the structural aspects of facilities composed of above-ground and buried pipeline systems and of storage tanks of different types and uses, as well as for independent items, such as for example single water towers serving a specific purpose or groups of silos enclosing granular materials, etc. (3) This standard 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. For some types of tanks and silos, it also provides detailed methods of assessment and verification rules. (4) This standard may not be complete for those facilities associated with large risks to the population or the environment, for which additional requirements are the responsibility of the competent authorities. This standard is also not complete for those construction works which have uncommon structural elements and which require special measures to be taken and special studies to be performed to ensure earthquake protection. In those two cases the present standard gives general principles but not detailed application rules. NOTE The National Annex may specify additional requirements for facilities associated with large risks to the population or the environment. (5) Although large diameter pipelines are within the scope of this standard, the corresponding design criteria do not apply for apparently similar facilities, like tunnels and large underground cavities. (6) The nature of lifeline systems which often characterizes the facilities covered by this standard requires concepts, models and methods that may differ substantially from those in current use for more common structural types. Furthermore, the response and the stability of silos and tanks subjected to strong seismic actions may involve rather complex interaction phenomena between soil-structure and stored material (either fluid or granular), not easily amenable to simplified design procedures. Equally challenging may prove to be the design of a pipeline system through areas with poor and possibly unstable soils. For the reasons given above, the organization of this standard is to some extent different from that of other Parts of EN 1998. This standard is, in general, restricted to basic principles and methodological approaches. NOTE Detailed analysis procedures going beyond basic principles and methodological approaches are given in Annexes A and B for a number of typical situations. (7) In the formulation and implementation of the general requirements, a distinction has been made between independent structures and redundant systems, via the choice of importance factors and/or through the definition of specific verification criteria. (8) If seismic protection of above-ground pipelines is provided through seismic isolation devices between the pipeline and its supports (notably on piles), EN 1998-2:2005 applies, as relevant. For the design of tanks, silos, or individual facilities or components of pipeline systems with seismic isolation, the relevant provisions of EN 1998-1:2004 apply.
