Sentence 9.20.8.4.(1)

Intent 1:

To limit the probability that masonry walls will be unable to resist the concentrated loads imposed by beams or columns, which could lead to cracking of masonry.

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.
