 Highlight ID: 1638 | Approval of Cross Laminated
Timber Shear Wall System in U.S. Codes Cross Laminated Timber (CLT) is an innovative mass timber product that has now been commonly accepted as a new generation engineered wood product with great potential to expand the wood building market. With the introduction of CLT to the US constr ... |
 Highlight ID: 1672 | Evaluating Fire Performance of
Adhesives used in Cross-Laminated Timber Our research focuses on the study of how adhesives used to hold wood composites together perform under fire to ensure strong, fire-safe construction. ... |
| Publication Year: 2019 | |
 Highlight ID: 1334 | Development of a Heavy Timber Buckling-Restrained Brace for Tall Wood Buildings Recent advancements in timber technologies are pushing mass timber systems into larger commercial-scale markets where steel and concrete systems dominate the landscape. One such market, Buckling-restrained braced frames (BRBFs), is a newer type of se ... |
 Highlight ID: 1333 | Earthquake Resistant Cross Laminated Timber Shear Wall System High and mid-rise wood building are only possible because of the development of an innovative mass timber product called Cross Laminated Timber (CLT). CLT has now been commonly accepted as a new-generation engineered wood product with great potential ... |
| Publication Year: 2018 | |
 Highlight ID: 1301 | Wood Adhesives at High Temperatures Researchers examined the performance of finger-jointed lumber to understand how it performs in fire. ... |
| Publication Year: 2016 | |
 Highlight ID: 657 | Seismic Performance of Cross-Laminated Timber Buildings Cross-laminated timber (CLT) buildings are becoming popular in earthquake regions of the United States, but structural engineers need new design methods. Forest Service research is striving to develop methods to design CLT buildings to six stories an ... |
| Publication Year: 2013 | |
 Highlight ID: 439 | Wood Construction Goes Beyond Its Traditional Roots As interest in sustainable building options continues to grow. Wood construction is going beyond its traditional roots in housing and expanding into mid-rise, high-rise, and non-residential applications. To support this trend, a new U.S. guide for th ... |
| Publication Year: 2010 | |
 Highlight ID: 170 | Centennial Edition, Wood Handbook—Wood as an Engineering Material The Wood Handbook—Wood as an Engineering Material serves as a primary reference document for a wide variety of users-from the general public through architects and design engineers who use wood in highly engineered structures. ... |

| Exploring Construction Using Whole Trees Researchers at the Forest Products Laboratory (FPL) are testing trusses, which provide structural support for buildings, made from whole trees. One such truss, pictured above, had a clear span of 55 feet and was made from low-value red pine logs. Similar trusses will be installed in a commercial r... | 03-06-2015 |
| Soft?Story Woodframe Buildings: In a new paper in the Proceedings for the American Society of Civil Engineers (ASCE) 2014 Structures Congress, FPL's Douglas Rammer discusses wood work pertinent to earthquake-prone areas of the world. In the recently published paper, Overview of the NEES?Soft Experimental Program for Seismic Risk R... | 08-07-2014 |
 Historic Glued-Laminated Arches Evaluated for Structural QualityThe second glued-laminated structure built in the United States was constructed at the USDA Forest Products Laboratory (FPL) in Madison, Wis. "Building Two" was constructed in 1934 to demonstrate the performance of wooden arch buildings. At various times it acted as a supplementary laboratory, lectu... | 01-03-2014 |
| FPL Research Patented A patent titled “Method and Apparatus for Determining the Surface Area of a Threaded Fastener” was recently awarded to FPL researchers Douglas Rammer and Samuel Zelinka. The invention is a method for reliably determining the surface areas of threaded fasteners, such as wood screws, drywall scr... | 03-14-2012 |
