Seismic Performance Of Engineering Systems In Buildings
|Publication Date:||30 April 2009|
This Standard sets out the criteria for the seismic performance of engineering systems related to a building's function. It covers the design, construction, and installation of seismic restraints for these engineering systems. Verification of the supporting structure for gravity and seismic actions is outside the scope of this Standard.
For engineering systems which enter or exit the building through foundations into the surrounding ground, only those items within one metre outside the footprint of the building are included.
The provisions of the Standard may be used for services in new or existing buildings, and for the purpose of retrofitting engineering systems into existing buildings.
The following items are included in the scope of this Standard, except as specifically excluded in 1.1.2:
(a) All engineering systems necessary to ensure compliance of the building with the New Zealand Building Code;
(b) All engineering systems essential for the normal functioning of the building; and
(c) Building Compliance Schedule items, such as emergency lighting.
The following items are excluded from the scope of this Standard:
(a) Engineering systems in buildings of importance level 5, as defined in AS/NZS 1170.0;
(b) Individual components with a mass exceeding 20% of the combined mass of the component and the building structure, and with a period of greater than 0.2 seconds;
(c) Items supported on the ground independently of the building, and external to the building;
(d) Lifts (including guide rails) and escalators;
(e) Contents of buildings including portable appliances, and items which are not attached to the building structure;
(f) Fire sprinkler system pipework; and
(g) Suspended ceilings.
