Back9.23.14.4.(1)

ATTRIBUTION:

Functional Statement:

F22

To limit movement under expected loads and forces.

Objective:

OS3.1

 

APPLICATION:

Orientation of plywood used as subflooring, 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 inappropriate orientation of or aligned joints in plywood subflooring, which could lead to inadequate strength between joists, which could lead to an inability to resist expected gravity loads, which could lead to:
  • the excessive deflection of subfloors, or
  • sagging or cracking of flexible or brittle finished floor between floor joists.
This is to limit the probability of an uneven walking surface, which could lead to persons tripping or falling, which could lead to harm to persons.

INTENT:

To limit the probability of inappropriate orientation of or aligned joints in plywood subflooring, which could lead to inadequate strength between joists, which could lead to an inability to resist expected gravity loads, which could lead to excessive deflection, which could lead to the space being unsuitable for its intended use.

APPLICATION:

Orientation of plywood used as subflooring, 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 inappropriate orientation of or aligned joints in plywood subflooring, which could lead to inadequate strength between joists, which could lead to an inability to resist expected gravity loads, which could lead to excessive movement, vibration or deflection, which could lead to negative effects on the psychological well-being of persons.
