9.20.17.1.(1)

Intent 1:

To limit the probability of an insufficient thickness of concrete in walls, insufficient bearing of supported walls, or eccentric loads on the wall, which could lead to an inadequate resistance to lateral earth pressure or an inability to support transverse or gravity loads, which could lead to concrete cracking.

This is to limit the probability of:

• compromised structural integrity of flat insulating concrete form wall construction, or
• where flat insulating concrete form wall construction is part of an environmental separator, the displacement or failure of required environmental separation elements, which could lead to deterioration.

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.
