9.20.8.4.(5)

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 excessive deflection or vibration of floors.

For floors and elements supporting floors, this is to limit the probability of persons losing their balance, tripping or falling, which could lead to harm to persons.
