Fire Behavior

 
NFPA's Fire Sprinkler Initiative offers free reports on how fire reacts to today's homebuilding materials.

Performance of Protected Ceiling/Floor Assemblies and Impact on Tenability with a Basement Fire Scenario 
National Research Council Canada, 2011
Following a previous report by the National Research Council Canada, which had focused on the fire performance of unprotected floor assemblies above a basement and impact on occupant safety in single-family houses, this study was conducted to investigate the fire performance of protected ceiling/floor systems in a basement fire scenario.

Fire Performance of Houses. Phase I. Study of Unprotected Floor Assemblies in Basement Fire Scenarios 
National Research Council Canada, 2008
The report examines fires in single-family houses to determine factors affecting life safety. Studies examine the typical sequence of events, including smoke alarm activation, onset of untenable conditions, and structural failure of test assemblies. The full-scale experiments address the life safety and egress of occupants from the perspective of tenability for occupants and structural integrity of structural elements, such as egress routes.

Structural Stability of Engineered Lumber in Fire Conditions
Underwriters Laboratories, 2008
Repeated concerns has been expressed within the fire service community regarding the structural performance of lightweight wood construction during a fire as compared to traditional construction. Conclusions of the research project included recognition of the need for fire performance data and the need for training focusing upon the fire performance of lightweight wood construction.

A Technical Analysis: The Performance of Composite Wood Joists Under Realistic Fire Conditions 
Tyco Fire Suppression & Building Products, 2008
Many residential structures are now being built using lightweight construction materials such as composite wood joists or engineered wood truss systems, instead of traditional solid-sawn lumber. These materials have many advantages, but there is some indication that they do not provide equivalent performance compared to traditional building techniques when subject to the loading imposed by structure fires.
