OS2 Structural Safety



Intent 1:

To limit the probability that:

  • the loads for which stairs and ramps are designed will not take into account probable accumulations of people and objects on the floor or roof surface in the context of use and occupancy, and
  • the live load on stairs and ramps will be less than the accepted minimum value in the context of use and occupancy.

This is to limit the probability of structural failure, which could lead to harm to persons.
