Do Your Floor Truss Chord Splices Meet Your Design Requirements? Glenn Traylor It seems like a simple thing—connect lumber together with connectors creating a top or bottom chord for your floor trusses that exceed your lumber length inventory. It’s one of the simplest applications of metal connector plates. But, while the task seems obvious, there are several... Read More December 2023 Issue #15293 Page 31
How Do I Maintain Lumber Grade Qualifications When I Cut Off the Grade Stamp? Glenn Traylor The past twenty years have brought many changes to the Metal Plate Connected Wood Truss Industry. These changes require manufacturing to change too, as the entire process continues to evolve and mature. Here is one situation where changes in manufacturing are necessary. Not too long ago,...

How Can We Understand Quality? Glenn Traylor How can we understand quality? September brings your chance to find out! At BCMC in Columbus last year, our Timber Products Inspection booth gave all attendees the chance to test their skills and acumen for Quality Assurance. This year at BCMC in Indianapolis, we’re holding the competition... Read More September 2023 Issue #15290 Page 33
“Person Loading” of Chords Without Structural Wood Sheathing Frank Woeste The National Design Standard for Metal Plate Connected Wood Truss Construction, ANSI/TPI 1-2022 has been updated to require a design load check that accounts for a Person Loading of a roof truss chord without structural wood sheathing. As discussed in the ANSI/TPI 1 Commentary, this loading... Read More September 2023 Issue #15290 Page 94
Floor Truss Technology, Part III: Floor Design Intricacies Joe Kannapell 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... Read More August 2023 Issue #15289 Page 10
Why is the Gaps Limitation So Important to Truss Fabrication? Glenn Traylor 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... Read More August 2023 Issue #15289 Page 35

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... Read More August 2023 Issue #15289 Page 90
Should We Seal All Engineered Drawings? Glenn Traylor Recently, while conducting an ANSI/TPI audit, a splice caught my eye. When I investigated further, I realized that the bottom chord of the truss I was investigating had a very short, 2” chord segment. I immediately assumed the truss builders had cut a short block to make up for a miss-cut... Read More May 2023 Issue #15286 Page 37
