Functional Statement:

F20

To support and withstand expected loads and forces.

F22

To limit movement under expected loads and forces.

F20

To support and withstand expected loads and forces.

F22

To limit movement under expected loads and forces.

Objective:

OS2.1, OS2.5, OS2.5, OS2.3

 

APPLICATION:

Minimum dimensions of sill plates supporting floors, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.].

INTENT:

To limit the probability of:
  • inadequate bearing length for the supported framing,
  • inadequate bending strength, or
  • inadequate thickness.
This is to limit the probability of an inability to resist expected gravity, lateral and wind-uplift loads, which could lead to:
  • crushing of sill plates,
  • failure of sill plates, or
  • pull-through or inadequate penetration of fasteners, which could lead to failure of connections.
This is to limit the probability of inadequate support for or anchorage of floor assemblies.
This is to limit the probability of compromised structural integrity, which could lead to:
  • the structural collapse of wood-frame construction, or
  • where wood-frame construction supports or is part of an environmental separator, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity.
This is to limit the probability of harm to persons.
