9.23.14.7.(2)ATTRIBUTION:
Functional Statement:
F22
To limit movement under expected loads and forces.
Objective:
OS3.1
APPLICATION:
End support for lumber subflooring used 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 end support, which
could lead to inadequate stiffness or strength, 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.

APPLICATION:
End support for lumber subflooring used 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 end support, which
could lead to inadequate stiffness or strength, 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:
End support for lumber subflooring used 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 end support, which
could lead to inadequate stiffness or strength, 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.
