The study meticulously documents panel characteristics, including average moisture content (MC) for both White-fir and Douglas-fir, alongside controlled environmental conditions of temperature and relative humidity (RH). A total of twelve panels were tested, differentiating between Melamine-Urea-Formaldehyde (MF) and Polyurethane (PUR) adhesives, and employing either 3-ply or 5-ply lamellae structures. The data presented highlights significant variations in moisture content across different species and panel constructions, providing crucial insights into material behavior under specific environmental stresses. This research is vital for advancing the understanding of structural wood product capabilities, particularly in developing robust and reliable construction methods using diverse timber resources. The findings are intended to inform industry standards and engineering practices for mass timber construction, ensuring optimal performance and durability in a range of applications.","| Panel \\# | Adhesive | lamellae | Average White-fir MC% | Average Douglas-fir MC% | Temp (F) | RH% |\n| --- | --- | --- | --- | --- | --- | --- |\n| 1 | MF | 3 ply | 9.7 | 15.1 | 63 | 32 |\n| 2 | MF | 5 ply | 11.0 | 16.5 | 63 | 32 |\n| 1 | PUR | 3 ply | 9.7 | 14.9 | 63 | 27 |\n| 2 | PUR | 3 ply | NA | 13.6 | 63 | 26 |\n| 3 | PUR | 3 ply | 10.2 | 12.6 | 63 | 36 |\n| 4 | PUR | 3 ply | 9.6 | 11.1 | 63 | 35 |\n| 5 | PUR | 3 ply | 8.9 | 10.0 | 63 | 32 |\n| 6 | PUR | 3 ply | 8.4 | 12.1 | 63 | 29 |\n| 7 | PUR | 5ply | 8.6 | 12.6 | 63 | 23 |\n| 8 | PUR | 5 ply | 8.4 | 10.7 | 61 | 32 |\n| 9 | PUR | 5 ply | 8.9 | 11.8 | 61 | 31 |\n| 10 | PUR | 5 ply | 8.3 | 11.4 | 63 | 28 |\n| 11 | PUR | 5 ply | 9.6 | 13.9 | 61 | 31 |\n| 12 | PUR | 5 ply | 10.1 | 14.3 | 63 | 31 |","cbCaidmii7ULS7Vb","https://ap.wps.com/l/cbCaidmii7ULS7Vb","pdf",5441830,2,1,49,"English","en",105,"# OSU Draft Final Report\n## CLT Layup Tests Using Mixed Fir Species\n### Panel Test Data\n*   Adhesive types (MF, PUR)\n*   Number of lamellae (3-ply, 5-ply)\n*   White-fir and Douglas-fir average Moisture Content (MC)\n*   Environmental conditions (Temperature, RH)","[{\"question\":\"What types of adhesives were used in the CLT layup tests?\",\"answer\":\"The tests utilized two types of adhesives: Melamine-Urea-Formaldehyde (MF) and Polyurethane (PUR).\"},{\"question\":\"What were the average moisture content percentages for White-fir and Douglas-fir?\",\"answer\":\"The average moisture content varied across panels, with White-fir ranging from approximately 8.3% to 11.0% and Douglas-fir from 10.0% to 16.5%.\"},{\"question\":\"What environmental conditions were maintained during the tests?\",\"answer\":\"The tests were conducted under controlled environmental conditions with temperatures around 63°F (17°C) and relative humidity (RH) levels ranging from 23% to 36%.\"}]","Full 13-D-I CLT Layup Tests Using Mixed Fir Species -
