NZ & Australian Seismic Code


The loadings Standard which includes seismic considerations, particularly NZS 1170 Part 5:2004 Earthquake actions – New Zealand assists in defining the loads for buildings.

NZS 1170 Part 5:2004 Earthquake actions – New Zealand is a Standard that has two core functions:

  • to provide methods for structural engineers to determine earthquake loading levels and specifications
  • to determine the seismic design loads for specific areas of New Zealand.

Design Standards for construction materials such as timber, steel, concrete, and earth-building are developed in alignment with loading Standards to guide design tolerances.
