This TECHnote examines the statutory requirements for seismic restraint which must be considered for non-structural components and internal fixings, and the relevant provisions within NATSPEC.

Although seismic design actions are generally considered the sole responsibility of the structural engineer, the National Construction Code (NCC), through the citation of the AS/NZS 1170 series of standards, also requires architects, building services engineers and contractors to take seismic design actions into account.

The requirements for non-structural elements exposed to external conditions, including wind, snow and ice are not included in this TECHnote.
