  4. OH4
  5. OS3
  6. OS1

Objective

OS2 Structural Safety

Attribution

[F20-OS2.3]Applies to elements that support or are part of an environmental separator.

Intent

Intent 1:

To limit the probability of:

  • an excessive loss of water due to evaporation,
  • the freezing of concrete before the initial set,
  • slowed hydration of the concrete, or
  • the freezing and expansion of the excess water not used in hydration.

This is to limit the probability of:

  • a failure to develop sufficient compressive strength before building loads are applied,
  • shrinkage and cracking, or
  • the failure of internal bonds.

This is to limit the probability of compromised structural integrity, which could lead to:

  • structural failure, or
  • where concrete supports or is used in an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

This is to limit the probability of harm to persons.
