Structural Stability of Engineered Lumber in Fire Conditions
Examining the impact of engineered floor systems on the time to collapse and firefighter safety
Overview

Under a U.S. Department of Homeland Security (DHS) Assistance to Firefighter Grant, UL, in collaboration with the Chicago Fire Department, Michigan State University, and the International Association of Fire Chiefs, completed a fire research study to understand firefighters hazards posed by the use of lightweight construction of wood trusses and engineered lumber in roof and floor designs. This material is increasingly replacing conventional solid joist construction in residential structures; this project investigated and compared the fire performance of each. The tests, in combination with fire performance data on lumber, enable fire professionals to better interpret hazards and assess safety of building occupants and firefighters.
