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
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

Including a Commentary & Appendices, this standard is available for purchase in print and... Read More August 2023 Issue #15289 Page 90
Are We Designing Our Components to Benefit Our Truss Builders and End Users? Glenn Traylor Many years ago, early in my career as a truss designer, I was interrupted by the production manager. He loudly entered my office with a piece of 2 x 12 and a circular saw and abruptly slammed both on top of my drafting table that was sporting a newly created truss layout. (We did not have...

Are You Providing Enough Information to Avert Failures? Glenn Traylor Recently, when a building owner started getting leaks in the roof and noticed unusual variations in the ceiling, I was asked to do an inspection to determine the best way to correct a deflection problem. Upon inspection, it was very evident that the roof trusses had not been installed correctly... Read More June 2023 Issue #15287 Page 37
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
Should We Consider “Delivery” Load Cases? Glenn Traylor Years ago, truss design was focused on a simple calculation that determined the final forces that would be considered to be imparted on a truss component. These simple forces were used to determine the design. Things like snow, wind, and building materials weights were generally the only... Read More April 2023 Issue #15285 Page 35
Does Your Plant Have a Culture of Quality? Glenn Traylor Quality, productivity, and speed are intertwined and impact each other. My previous article, Where is Your Focus on Manufacturing?, emphasizes that improving quality starts with implementation of the ANSI/TPI 1 standard—and, with that process, you will improve proficiency and speed. The... Read More March 2023 Issue #15284 Page 35
Has Your Guideline Shifted? Glenn Traylor Recently after receiving a phone call from a client, I reflected on our conversation. I was a little caught off guard with the direction the conversation took and felt like I needed to make a few issues clear. And, it has led me to reflect on boundaries and guidelines – why they exist and... Read More February 2023 Issue #15283 Page 35
