Establishing a truss design process that progresses seamlessly from start to finish serves as a critical backbone for efficiency and ensures essential quality control measures. While individual processes might vary from designer to designer, here is a sample step-by-step process. Resist the...

In last month’s article, Designing for Resiliency, I present some of my thoughts on how changing the design approach for wood trusses could aid in making future homes more resilient to the types of climate extremes that seem to be ahead of us. Whether you think that climate change is a...

Sponsored by the Virginia Tech Continuing and Professional Education program, a three-day program on light-frame and mass timber construction design topics will be offered on May 14–16, 2024 in Blacksburg, VA. Joining me as instructors this year are Scott D. Coffman, PE, John Holland, MBA,...

As I write this, I am sitting inside a warm office in Northern Ontario, looking out the window at near blizzard conditions, with heavy snow falling and –35° wind chill. Although it is very unpleasant outside, this isn’t necessarily unusual weather for this location, but what is...

The advent of floor trusses gave us new insights that continue to be refined today. They also gave us a peek into whole house design with the promise of a fully componentized house. For the first time, they challenged us to build something that people could live on top of, rather than just...

ANSI/TPI 1 is a practical guide to manufacturing metal plate connected wood truss. It considers rational expectations and reasonable manufacturing capabilities that help ensure a sound product. Due to the nature of wood, cutting equipment and processes gaps do occur. These gaps can cause...

As I approach four decades in this industry (!), the list of building code and design requirements that seem odd to me continues to grow. I am the first to acknowledge that the primary goal in designing a home is, and should be, occupant safety. But there are some requirements and...

After more than three years in development, I’m pleased to announce the publication of ANSI/TPI 1–2022 National Design Standard for Metal Plate Connected Wood Truss Construction. Including a Commentary & Appendices, this standard is available for purchase in print and...

“Change is the only constant in life” and “When you are finished changing, you are finished” are quotes from the ancient Greek philosopher Heraclitus and Benjamin Franklin, respectively. I’m reminded of them as I review the numerous changes to codes and standards...

Once again, Virginia Tech will be offering its popular two-day course on topics related to wood construction. This year’s course, to be held on April 26–27, will focus on practical code-conforming design of wood structures based on provisions of the 2018 National Design...
