Research Highlights

Evaluating Fire Performance of Adhesives used in Cross-Laminated Timber

Year: 2020
Our research focuses on the study of how adhesives used to hold wood composites together perform under fire to ensure strong, fire-safe construction.

Approval of Cross Laminated Timber Shear Wall System in U.S. Codes

Year: 2020
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 construction market and the current modern urbanization tr...

Earthquake Resistant, Cross Laminated Timber Shear Wall System

Year: 2019
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 is now commonly accepted as a new-generation engineered wood product with great potential to expand the wood building market.  With the introduc...

Development of a Heavy Timber Buckling-Restrained Brace for Tall Wood Buildings

Year: 2019
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, is a newer type of seismic-force-resisting system used in modern building desi...

Wood Adhesives at High Temperatures

Year: 2018
Researchers examined the performance of finger-jointed lumber to understand how it performs in fire.

Seismic Performance of Cross-Laminated Timber Buildings

Year: 2016
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 and beyond that will withstand earthquakes.

Wood Construction Goes Beyond Its Traditional Roots

Year: 2013
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 the early adoption of cross-laminated timber, an inn...

Centennial Edition, Wood Handbook—Wood as an Engineering Material

Year: 2010
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.
