9.20.11.6.(1)

Objective

OP2 Structural Sufficiency of the Building

Attribution

[F20-OP2.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability of insufficient depth of concrete or masonry for an adequate bond with anchor bolts, which could lead to inadequate withdrawal resistance, which could lead to an inability to resist expected wind loads, which could lead to overturning, lifting, sliding or excessive deflection of the superstructure.

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

  • structural failure of the superstructure,
  • where piers support an environmental separator, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, or
  • an inability to resist expected loads, which could lead to:
    • the excessive movement or deformation of walls, or
    • the excessive deflection or vibration of floors.

This is to limit the probability of:

  • the space being unsuitable for its intended use,
  • compromised operation of windows or doors, or
  • damage to the building.

Intent 2:

To direct Code users to Sentence 9.15.2.3.(4), which contains requirements for piers.
