Intent
Intent 1: 
To limit the probability of an inadequate resistance to lateral soil loads, which could lead to damage to floors or foundation walls.
This is to limit the probability of:
  • the compromised structural integrity, or
  • where concrete slabs serve as an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements, which could lead to compromised structural integrity.
For floors and elements supporting floors, this to limit the probability of excessive movement, deflection or vibration of floors, which could lead to negative effects on the psychological well-being of persons.
