The recent approval of the 2018 International Building Code (IBC) and International Residential Code (IRC) is of keen interest to professionals in the construction industry as it often means expanded options for structural applications. In support of these two codes, the American Wood Council...

With today’s complex profiles and configurations, many truss fabricators have been relying on staples to set assembly member contact and relationships. Stapling serves as a temporary means to insure tight joints and accurate locations. Often times, however, because of the ease of multiple...

The knowledge we take for granted today on MSR lumber is due in large part to the pioneering work of Professor Robert Hoyle, P.E. In the early 1960s at Potlatch Forest, Inc., he conducted basic research on the relationship between stiffness and strength of lumber, paving the way for the MSR...

Building officials are the gatekeepers to building construction. To approve any construction, including where wood is the principal product, they need to know a lot of information. The American Wood Council aims to make the job of building code official a little easier when it comes to knowing...

Background The model International Residential Code (IRC) permits a design live load of 30 psf for “sleeping rooms.” The model codes specify 40 psf for all other rooms. Of the annoying floor vibration complaints we have received, the most common scenario stems from the use...

The future is here. It is common knowledge that wood is a renewable and environmentally friendly building material. There are two types of wood-framing methods in North America. The most common method for residential construction is light-frame construction using either balloon-framing or...

Mass timber, including cross-laminated timber (CLT), has been in use worldwide for over 15 years, but most notably in Europe. However, North American designers and engineers are increasingly showing interest in picking up the trend. Building with mass timber for taller buildings has...

Unlike solid-sawn lumber, the mechanical properties of some materials are greatly affected by ambient temperatures and solar-radiation heating, as depicted by the photograph. However, while the engineering design properties of solid-sawn lumber are not affected by ambient temperatures, they can...

Modern technology helps to simplify our daily lives in many ways with the touch of a button—and now, today’s technology plays an important role in the way the wood construction industry is improving speed, efficiency and safety, and even compliance with the latest building...

Construction is rebounding, and with it the need to invest in education for safe and sustainable structures is more important than ever. As manufacturers of wood products, many in our industry have the opportunity to directly engage with those on the front lines of construction who are often...
