Intent

Intent 1:

To limit the probability that structural steel members will fail prematurely when exposed to fire, which could lead to the failure or collapse of rated construction supported by the structural steel members [e.g. floor, roof and wall assemblies] during the time required to achieve occupant safety and for emergency responders to perform their duties, which could lead to harm to persons.

Intent 2:

To limit the probability that structural steel members will fail prematurely when exposed to fire, which could lead to the failure or collapse of rated construction supported by the structural steel members [e.g. floor, roof and wall assemblies], which could lead to the spread of fire from a lower storey of a building to an upper storey during the time required to achieve occupant safety and for emergency responders to perform their duties, which could lead to harm to persons.
