The Seismically Resilient Non-structural Elements fact sheets aim to assist building services industries to achieve compliance with the New Zealand Building Code and encourage a more consistent approach to the design and installation of seismically resilient non-structural elements, components and systems in New Zealand buildings.
This fact sheet is regarding design criteria.
NZS 4219:2009 states that the location, design, construction and installation of engineering systems should reduce life and injury hazards and protect property and systems from damage or loss of function. To achieve this, the standard requires engineering systems to be designed, constructed and installed so that the following criteria are met:
- Components representing a hazard (classification P1, P2 and P3) will not collapse, rupture or lose support after an ultimate limit state (ULS) earthquake.
- Components required for emergency evacuation (classification P4) will not collapse, rupture or lose support after a ULS earthquake.
- Components required for operational continuity (classification P5) within buildings of importance level 4 are restrained in a manner so that the system is able to continue to perform its functions after a serviceability limit state 2 (SLS2) earthquake.
- All components are restrained in a manner so that the system retains its structural and operational integrity without requiring repairs after a serviceability limit state 1 (SLS1) earthquake.
