Intent
Intent 1: 
To limit the probability of:
  • an inability to resist expected wind loads, which could lead to overturning, lifting or sliding of the superstructure off the foundation, and
  • where the superstructure is required to provide lateral support for the foundation, an inability to resist expected lateral earth pressure loads, which could lead to:
    • cracking or differential movement of the foundation, or
    • compromised structural integrity of the foundation, which could lead to deflection or deformation of the superstructure.
For floors and elements supporting floors, this is to limit the probability of:
  • compromised structural integrity, or
  • where members support or are part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to deterioration.
This is to limit the probability of excessive deflection or vibration of floors, which could lead to persons losing their balance, tripping or falling, which could lead to harm to persons.
