Intent 1:

To limit the probability that the amount and spacing of horizontal reinforcement will not be adequate to ensure nominal ductility, which could lead to the cracking or displacement of foundation walls.

This is to limit the probability of:

• compromised structural integrity, or
• where elements support or are part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

For floors and elements supporting floors, this is to limit the probability of excessive movement, deflection or vibration, which could lead to negative effects on the psychological well-being of persons.
