EN 1998 - Seismic actions

EUROCODE 8 is subdivided into the following parts:

ÖNORM EN 1998-1 

General rules, seismic actions and rules for buildings

ÖNORM EN 1998-2 

Bridges

ÖNORM EN 1998-3

Assessment and retrofitting of buildings

ÖNORM EN 1998-4

Silos, tanks and pipelines 

ÖNORM EN 1998-5

Foundations, retaining structures and geotechnical aspects

ÖNORM EN 1998-6

Towers, masts and chmineys

EUROCODE 8 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.

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. Special structures, such as nuclear power plants, offshore structures and large dams, are beyond the scope of EN 1998.

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.
