Truss Lumber: Checking the Moisture Content
The lack of attention to the moisture content (MC) of lumber used in truss manufacturing can cause or contribute to in-service performance issues. Mr. Glenn Traylor’s fine article in the September issue of The Advertiser, “Does Your Lumber Have a Shelf Life?”, was greatly...
Now’s the Time to Promote Safe, Sustainable Construction
October is a busy time for the wood products industry. There are not one but three weeks dedicated to national observances important to the safe built environment.
Sunday, Oct. 7 – Saturday, Oct. 13: National Fire Prevention Week
The National Fire Protection Association’s Fire...
Still Using Lag Screws? Consider Self-Tapping Wood Screws Instead
Aram Khachadourian, P.E.
Lag screws are traditionally specified for many structural loads in wood construction. However, recent innovations in engineering for self-tapping wood screws have made them an increasingly popular, labor-saving alternative to lag screws. In the following, Aram Khachadourian, P.E., of Simpson...
Updated Report Helps Engineers, Designers Calculate Fire Resistance of Wood Members and Assemblies
Increasing use of mass timber as a competitive building product in the construction marketplace requires sound design guidelines to ensure safe, efficient, and economic use of wood products. AWC fire research on mass timber conducted over the last year, with support from the Softwood Lumber...
New Codes are Coming
With the New Year comes new International codes, IBC and IRC 2018 (referred to as the I-Codes), and fortunately, few changes to truss designs. These changes are the result of the revised design criteria contained in ASCE 7–16, which IBC 2018 relies upon.
Very few jurisdictions will...
2018 Wood Design Standards Available Online
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...
Can Staple Use Be Too Much of a Good Thing?
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 Pioneer of MSR Lumber
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...
Making Code Official Connections
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...
