AbstractIn North America, lightweight wood-framed assemblies are commonly used in residential building construction for their light weight and low construction costs. These assemblies, which form the walls and floors of building compartments, are normally required to provide adequate fire resistance in order to maintain building integrity, to reduce fire spread from one fire compartment to another, and to provide for the safe egress of building occupants. The fire resistance can be determined by tests or by calculation models. In testing, a barrier is subjected to a fire test conducted in accordance with procedures outlined in standards. In calculation, fire resistance can be evaluated using numerical models or simplified formulas. With the advent of performance-based codes, where compliance with a set of objectives must be achieved, validated fire resistance models have become essential.
