9.20.12.1.(2)

Intent 1:

To limit the probability of excessive eccentricity of loads, which could lead to foundation walls being unable to resist gravity loads or earth pressure from the exterior, which could lead to cracking of foundation walls and supported walls or floors.

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.
