Intent 1:
To limit the probability that pilasters will be
unable to resist the loads imposed by beams or columns, which could
lead to structural failure of unit-masonry pilasters and cracking
of masonry walls.
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, 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.
