9.23.11.2.(1)

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:

  • inadequate distribution of vertical loads to and from studs,
  • inadequate lateral support for the ends of the studs, or
  • inadequate diaphragm action of plates.

This is to limit the probability of the excessive deflection of walls.

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.
