9.23.14.4.(3)

Objective

OS1 Fire Safety

Attribution

[F20,F22-OS1.2]Applies to assemblies required to provide fire resistance.

Intent

Intent 1:

To limit the probability of the inadequate connection of rafters at ridges, which could lead to:

  • an inability to transfer expected gravity loads or positive wind loads at their upper ends, or
  • an inability to resist expected negative wind loads, which could lead to tension separation of roof peaks.

Where assemblies are required to provide fire resistance, this is to limit the probability of compromised fire resistance of the assembly, which could lead to harm to persons.

Intent 2:

To exempt situations from the application of Sentence 9.23.14.4.(2) where the roof framing on opposite sides of the peak is assembled separately.
