9.23.6.1.(1)
OS2OP2OH1OH4OS3
ObjectiveOS2 Structural Safety
Attribution
[F20,F22-OS2.3] Applies to elements that support or are part of an environmental separator.
Application
Application 1: 
Anchorage of building frames to foundations, in wood-frame constructions to which Section 9.23. applies [see Sentence 9.23.1.1.(1) for application of Section 9.23.].
Exceptions: 
except:
  • as exempted where analysis of wind and earth pressures shows that anchorage to the foundation is not required, and
  • as stated in Sentence 9.23.6.3.(1), which applies to the anchorage of smaller buildings.

Intent
Intent 1: 
To limit the probability of:
  • an inability to resist expected wind loads, and
  • where the superstructure is required to provide lateral support for the foundation, an inability to resist expected lateral earth pressure loads, which could lead to:
    • cracking or differential movement of the foundation, or
    • compromised structural integrity of the foundation.
This is to limit the probability of compromised structural integrity, which could lead to:
  • the structural collapse of the superstructure or the foundation, or
  • for environmental separators or construction that supports environmental separators, 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.
