compartmentation
The following are excluded from the definition of ‘element of structure’.
a. A structure that supports only a roof, unless either of the following applies.
i. The roof performs the function of a floor, such as for parking vehicles, or as a means of escape.
ii. The structure is essential for the stability of an external wall that needs to be fire resisting (e.g. to achieve compartmentation or for the purposes of preventing fire spread between buildings).
b. The lowest floor of the building.
c. A platform floor.
d. External walls, such as curtain walls or other forms of cladding, which transmit only self weight and wind loads and do not transmit floor load.
NOTE: In some cases, structural members within a roof may be essential for the structural stability system of the building. In these cases, the structural members in the roof do not just support a roof and must demonstrate the relevant fire resistance for the building as required by the note to paragraph 6.1 above.
