The structural Eurocodes are divided into packages by grouping Eurocodes for each of the main materials, concrete, steel, composite concrete and steel, timber, masonry and aluminium. This is to enable a common date of withdrawal (DOW) for all the rele

Following publication of the EN, there is a period of two years allowed for the national calibration p

During the coexistence period Member States will be encouraged to adapt their national provisions to withdraw conflicting national rules before the end of the coexistence period. The Commission in consultat

To enable EN 1998-2 to be used in the UK, the NDPs will be published in a National Annex, which will be made availab

There are generally no requirements in the UK to consider seismic loading, and the whole of the UK may be considered an area of very low seismicity in which the provisions of EN 1998-2 need not apply. However, certain types of struc
13、ture, by reason of their function, location or form, may warrant an explicit consideration of seismic actions. It is the intention in due course to publish separately background information on the circumstances in which this might apply in the UK. Cross-references The British Standards which impleme
