Abstract:

In order to have a better understanding of statistical distribution of firebrands' mass, size (projected area), and traveling distance, full-scale firebrand generation experiments were conducted. Full-scale structural components (fence, corner, and roof) and their assemblies were built from typical residential building construction materials. The samples were ignited and exposed to realistic gusty wind traces in a wind tunnel facility in the Insurance Institute for Business & Home Safety (IBHS) Research Center located in Richburg, South Carolina. Water pans were placed downwind to quench the flying firebrands immediately after landing. The distance between the center of the water pans in which the firebrands' landed and the front location of the burning sample was defined as the traveling distance. The firebrands were collected from the water pans and placed in an oven to reach zero percent moisture content. Dried firebrands were scattered on a white sheet. High-resolution pictures were captures of each sheet using a digital camera (Nikon D5600). Following that, an automated image processing algorithm using MATLAB was developed and employed to measure firebrand projected area. Using a digital balance (Sartorius H51, resolution of ±0.0001 gram), firebrand mass was measured. Experiments and raw data collection for this study were conducted from 2016-2017. The result was 50,571 firebrands collected and measured, with 24,149 from structural components and 26,422 from structural assemblies.
