OS3 Safety in Use


[F20,F22-OS3.1]Applies to floors and elements that support floors.


Intent 1:

To limit the probability of:

  • inadequate strength of individual members,
  • discontinuity of individual members, which could lead to compromised resistance to buckling, or
  • compromised load transfer among members.

This is to limit the probability:

  • that the column members will be unable to resist expected vertical loads, which could lead to buckling of individual members,
  • of compromised resistance to buckling, or
  • of unequal load sharing among members of built-up wood columns, which could lead to progressive structural failures of column members.

This is to limit the probability of:

  • compromised structural integrity, or
  • for environmental separators or elements supporting an environmental separator, the displacement or failure of required environmental separation elements, which could lead to the deterioration of building elements.

For floors and elements supporting floors, this to limit the probability of excessive deflection or vibration of floors, which could lead to a loss of balance, tripping or falling, which could lead to harm to persons.
