9.15.3.7.(1)

Intent 1:

To limit the probability of an insufficient plan area for column footings, which could lead to an inability to resist expected gravity loads, which could lead to compressive failure and excessive settlement of underlying soil, which could lead to structural damage to the foundation and the building, which could lead to an inability to support vertical building loads or lateral earth loads.

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.
