A couple years ago, I did a post on selecting holdown anchorage solutions. At the time, we had created a couple engineering letters that tabulated SSTB, SB and PAB anchor solutions for each holdown to simplify specifying anchor bolts. About a year later, a salesperson suggested we tabulate SSTB,...

The International Code Council (ICC) building code update process for the 2021 code cycle is officially underway! In late December, the ICC Tall Wood Building Ad-hoc Committee submitted a package of 19 proposed changes for the 2021 edition of the building code that would collectively allow...

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...

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...

While the International Residential Code (IRC) gives the structural requirements and prescriptive design data for residential framing, additional help for the non-engineer is available through the Wood Frame Construction Manual for One- and Two-Family Dwellings (WFCM) published by the American...

Truss designers be aware: energy codes are changing HVAC systems. Until recently, duct layouts were designed like truss layouts of the 1970s – hand-drawn on blue prints. Since Building Officials don’t require residential heating/AC layouts, you may have not known of collisions until...

In 2016, the California Occupational Safety and Health Administration (Cal/OSHA) proposed to significantly lower the permissible exposure limit (PEL) of wood dust from 5 milligrams per cubic meter (mg/m3) to 1 mg/m3. Earlier this year the Cal/OSHA Standards Board considered that proposal....

It’s been said that the World Wide Web is the wave of the future. Okay, maybe this is slightly outdated news, as it’s been 25 years since Bill Gates penned his internet tidal-wave memorandum, but it’s a good lead-in to this topic – web apps. More specifically, those apps...

With Hurricane Irma wrapping up, the cleanup after Hurricane Harvey’s devastation underway in Houston and more big storms already churning in the Atlantic, it seems like a good time to discuss hurricanes and high wind. There is a great deal of good information out there to help us better...

In the 1960s, Ed Ryan set basic standards for panelizing walls, and for decades his homebuilding company (now NVR Inc.) followed his lead. His standards also made it easy for us to provide his wall panel equipment. The name we gave it, “Panel-Rite,” would have pleased Ed, since he...
