The UK National Annex to BS EN 1998-1:2004 standard provides specific requirements for the design of buildings and civil engineering works in seismic regions. The standard is divided into 10 sections, with some sections dedicated to the design of buildings.

BS EN 1998-1 covers various aspects including basic performance requirements, compliance criteria, representation of seismic actions, combination with other actions, base isolation of structures, and general design rules for buildings. It also includes specific rules for different structural materials such as concrete, steel, composite steel-concrete, timber, and masonry.

The National Annex for the UK provides the UK's decisions on the Nationally Determined Parameters outlined in the subclauses of BS EN 1998-1:2004. It also specifies the UK's decisions on the status of informative annexes within the standard and references non-contradictory complementary information. This Annex ensures that the design requirements and guidelines are specific to the seismic conditions and design practices in the UK.
