Home Building Technology, Part X: Competing Connectors Joe Kannapell, PE In multiple jurisdictions across the country, building code authorities questioned the viability of the curiously shaped metal plates being used on trusses during the last half of the 1950s. In South Florida, for example, four radically different looking plates appeared, with different... Read More October 2025 Issue #17315 Page 10
Do You Know Your ANSI/TPI 1 Chapter 3 Numbers? Glenn Traylor Inspired by frequent requests for a quick reference, I’ve created a single-sheet ANSI/TPI 1 Chapter 3 guide—similar to a CliffsNotes version of the standard. Please note that important details are omitted; for a complete understanding, consult the full standard, National Design... Read More October 2025 Issue #17315 Page 33
Home Building Technology, Part IX: The Great Connector Joe Kannapell, PE Cal Jureit’s truss testing experience was but the first of three consequential steps that led him to invent the modern truss connector plate. Jureit’s second step was joining Truss Fabrications, Inc. (TFI), which furthered his knowledge of truss manufacturing, and focused his efforts... Read More September 2025 Issue #17314 Page 10
Home Building Technology, Part VIII: The Engineering Advantage Joe Kannapell, PE Where is the best location to start a business — the easiest place or the toughest? Choosing the easiest means you may or may not “have what it takes” to succeed in the toughest markets. But, by choosing the toughest, you may “set yourself up” to market yourself...

What are Your Options to Address Member-to-Member Gaps? Glenn Traylor A recent phone call has prompted me to address the issue of fixing gaps. There are some misunderstandings about what qualifies as a member-to-member gap, and the options to fix them are not always clear either. ANSI/TPI 1 recommends that members in a truss to touch each other when possible.... Read More August 2025 Issue #17313 Page 33
Home Building Technology, Part VII: Carol Sanford’s Quantum Leap Joe Kannapell, PE Carol Sanford came of age during the 1920s, inspired by his inventive father, during one of the most inventive periods in American history. He grew up in Canton, OH, then a center of steel and stamping industries. After graduating from the University of Cincinnati and an architectural school in... Read More July 2025 Issue #17312 Page 10
How Will the Changes to ANSI/TPI 1 Impact Your Truss Builders and In-House Inspectors? Glenn Traylor As we migrate from ANSI/TPI 1-2014 to ANSI/TPI 1-2022, it is important to discuss and be aware of Chapter 3 updates. These changes impact QC inspections and should be understood by your in-house QC inspector and your truss builders. The changes are in two categories in Chapter 3 — a...

Home Building Technology, Part VI: The Original Wood Truss Manufacturers Joe Kannapell, PE Although last month’s article in this series, “Home Building Technology, Part V: Early Truss Connection Innovators,” brought our story up to the post-war time period, we would be remiss without acknowledging the original truss manufacturers in greater detail. A small group of... Read More June 2025 Issue #17311 Page 10
Home Building Technology, Part V: Early Truss Connection Innovators Joe Kannapell, PE Three midcentury forces converged to form the truss business we know today. First came the deluge of demand for affordable housing after World War II. Then came the prefabbers who addressed that need with trusses. And finally came the connector that made trusses into a blockbuster... Read More May 2025 Issue #17310 Page 10
Is Plate Substitution the Most Common Error By Confused Truss Builders? Glenn Traylor Generally speaking, ANSI/TPI 1 makes common sense and is very logical. However, there are several items that can be a little confusing because they seem to defy logic. When we upgrade lumber per ANSI/TPI 1 Section 3.4.2, we know that lumber strength needs to be maintained in order to meet the... Read More May 2025 Issue #17310 Page 39
