DS/ENV 1998-1-1:1994 Eurocode 8: Design provisions for earthquake resistance of structures - Part 1-1: General rules - Seismic actions and general requirements for structures
1 Scope of Eurocode 8
(l)P Eurocode 8 applies to the design and construction of buildings and civil engineering works in seismic regions. Its purpose is to en-sure, that in the event of earthquakes
- human lives are protected,
- damage is limited,
- 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 probabilistic protection that can be provided to different categories of buildings 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.
To provide the necessary flexibility in this respect, Eurocode 8 contains a set of safety elements whose values are left to the National Authorities to decide so that they can adjust the level of protection to their respective optimal value.
(2)P Special structures with increased risks for the population, such as nuclear power plants and large dams, are beyond the scope of Eurocode 8.
(3)P Eurocode 8 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) Eurocode 8 is subdivided into various separate Parts, see 1.1.2 and 1.1.3.
2 Scope of Part 1-1
(1) Part 1-1 contains the basic requirements and compliance criteria applicable to buildings and civil engineering works in seismic regi-ons .
(2) In addition, Part l-l gives the rules for the representation of seismic actions and for their combination with other actions. Certain types of structures, dealt with in Parts 2-5, need complementing rules which are given in these Parts.
3 Further Parts of Eurocode 8
(DP Further Parts of Eurocode 8 include - in addition to Part 1-1 -the following:
- Part 1-2 contains general design rules relevant specifically to buildings,
- Part 1-3 contains specific rules for various structural materi-als and elements, relevant specifically to buildings,
- Part 1-4 contains provisions fcr the seismic strengthening and repair of existing buildings,
- Part 2 contains specific provisions relevant to bridges,
- Part 3 contains specific provisions relevant to towers, masts and chimneys,
- Part 4 contains specific provisions relevant to tanks, silos and pipelines,
- Part 5 contains specific provisions relevant to foundations, retaining structures and geotechnical aspects.
