  3. OH1
  4. OH4
  5. OS3

Objective

OS3 Safety in Use

Attribution

[F20-OS3.1]Applies to floors and elements that support floors.

Intent

Intent 1:

To limit the probability of:

  • an inability to resist expected wind and seismic 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 constructions supporting floors, this is to limit the probability of:

  • compromised structural integrity, or
  • for exterior floors or environmental separators supporting a floor, the excessive deformation, displacement or failure of required environmental separation elements, which could lead to deterioration, which could lead to further compromised structural integrity.

This is to limit the probability of excessive deflection or vibration, which could lead to persons losing their balance, tripping or falling, which could lead to harm to persons.

Intent 2:

To expand the application of Part 4, where construction is in high wind and seismic regions.
