Summary
This project will document the flammability of Douglas-fir and spruce-pine-fir CLT panel assemblies produced in the United States. Tests are being conducted on wall and floor panel assemblies with standard overlapping connections and produced with two different types of commonly-used adhesives. Sensors placed throughout panels will provide data about how fire affects the interior and exterior of a panel. A thermal imaging camera will provide information on how the structural integrity of panels is affected by fire and fire suppression activities.

Summary
The objective of this research was to determine the feasibility of using lumber from Northeastern U.S. forests and laminated strand lumber (LSL) in cross laminated timber (CLT). Three-layer 105 mm x 1.32 m x 2.45 m CLT panels consisting solely of Spruce-Pine-Fir (South) and 1.35E LSL were manufactured by hand. Four-point...
