Intent 1:
To limit the probability of an inability to resist
gravity, lateral or impact loads.
This is to limit
the probability of:
- compromised structural integrity of masonry construction,
- where masonry construction is part of an environmental
separator, the displacement or failure of required environmental separation
elements, which could lead to deterioration,
- in assemblies exposed to moisture or the exterior, damage
and 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, or
- damage to the building.
Intent 2:
Where masonry is used in fireplaces or chimneys,
to limit the probability of an inability to withstand high temperatures,
which could lead to cracking, which could lead to structural failure,
which could lead to damage to the building.
