Have You Taken the Quality Assurance Challenge? Glenn Traylor We have an annual tradition at the Building Component Manufacturers Conference (BCMC)—the Timber Products Inspection quality assurance challenge! This competition lets truss fabricators test their knowledge of ANSI/TPI 1 Chapter 3 requirements, and the winner receives a Yeti cooler. How... Read More October 2024 Issue #16303 Page 33
Are You Interpreting Member-to-Member Gaps Correctly? Glenn Traylor In a recent discussion with several very well-informed industry folks, it became clear to us that interpretation of member-to-member gaps may not be clear. In particular, we need to take a closer look at Chapter 3 Quality Criteria for the Manufacture of Metal-Plate-Connected Wood Trusses of... Read More September 2024 Issue #16302 Page 35
What Can We Learn From the Recent CrowdStrike Debacle? Glenn Traylor In the early morning hours of July 19, 2024, there was a major collapse of world commerce. According to the company CrowdStrike, a defect in a content update to its Falcon cybersecurity defense software for Windows caused a world-wide crash that impacted many businesses, most notably the...

What is Camber and Why is It Important? Glenn Traylor In the truss industry, camber refers to the gradual curvature of a chord member either naturally occurring or created to alleviate the natural deflection of a truss structure. That sounds simple enough, but there are key elements about camber that should be considered. Camber in Action All... Read More July 2024 Issue #16300 Page 33
Does Fire Retardant Lumber Require Special Handling? Glenn Traylor Fire retardant lumber, also called FRTW, is used when a project has a requirement to reduce the structures’ ability to burn and to reduce the structures’ contribution to the spread of fire. Most fire retardant materials also reduce the development of smoke and the release of... Read More June 2024 Issue #16299 Page 33
How Do You Determine Fabrication Tolerances During Design? Glenn Traylor How does a component manufacturer determine what fabrication tolerances should be used during truss design? To answer that question, we first need to clarify what is meant by “fabrication tolerance.” Per ANSI/TPI 1–2014, the guidance is 3.3.2 Fabrication Tolerance. All...

Do You Know the Frequent Non-Compliance Issue That’s “Easy” to Fix? Glenn Traylor The photo shows a 2 x 4 truss with an ANSI/TPI 1 non-compliance issue. This is something that never should have happened! Can you spot the problem? [For photo, See PDF or View in Full Issue.] If you shouted, “a missing connector,” then give yourself a gold star! As I was ranking... Read More April 2024 Issue #16297 Page 35
What is the Best Way to Handle Defects Under the Plated Area? Glenn Traylor Everyone who uses lumber in trusses understands that defects in lumber can impact truss performance in different ways. Some defects are not important but others will affect truss performance and can even cause truss failure. [For all photos, See PDF or View in Full Issue.] In the first photo,...

Can Eased Edge Lumber Usage Impact Truss Design? Glenn Traylor Originally intended as an improvement in lumber manufacturing, most dimensional lumber used for framing has a radius corner created during the planing process. The rounded corner radius is intended to make the lumber easier to handle and can improve the lumber’s performance because sharp... Read More February 2024 Issue #16295 Page 33
