Description

Sets out data and procedures for determining earthquake loads on structures and their components, and also minimum detailing requirements for structures. Domestic structures are covered in an Appendix.

Scope

This Standard sets out procedures for determining earthquake actions and detailing requirements for structures and components to be used in the design of structures. It also includes requirements for domestic structures.

Importance level 1 structures are not required to be designed for earthquake actions.

The following structures are outside the scope of this Standard:

• (a) High-risk structures.
• (b) Bridges.
• (c) Tanks containing liquids.
• (d) Civil structures including dams and bunds.
• (e) Offshore structures that are partly or fully immersed.
• (f) Soil-retaining structures.
• (g) Structures with first mode periods greater than 5 s.

This Standard does not consider the effect on a structure of related earthquake phenomena such as settlement, slides, subsidence, liquefaction or faulting.
