  4. OS1

Objective

OP2 Structural Sufficiency of the Building

Attribution

Intent

Intent 1:

To limit the probability of:

  • excessive width, which could lead to excessive shrinkage, which could lead to:
    • buckling or tearing of roofing, or
    • excessively wide gaps between boards, which could lead to puncturing of roofing,
  • unsupported end joints, which could lead to an inability to resist point loads from foot traffic, which could lead to differential deflection of unsupported sheathing board ends, which could lead to damage to roofing, and
  • aligned end joints, which could lead to discontinuity in the roof structure, which could lead to an inability to resist expected lateral or gravity loads, which could lead to excessive deflection, which could lead to damage to roofing.

This is to limit the probability of compromised structural integrity, which could lead to:

  • the structural collapse of wood-frame construction, or
  • precipitation ingress, which could lead to deterioration, which could lead to further compromised structural integrity of the roof.

This is to limit the probability of damage to the building.
