The Last Word: Can Crooked Lumber Defeat Robotics? Joe Kannapell, PE A robot visited the BCMC Show floor again this year, and, for the first time, really showed its stuff, picking truss plates like there was no tomorrow. And its dynamic demo couldn’t be missed, as House of Design (HoD) positioned their Nail Plate Picking Cell right at the exhibit’s... Read More October 2023 Issue #15291 Page 134
“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
Feed Any Component Saw with a Lumber PickLine Edmond Lim, P.Eng. Did you know that any existing automated saws output can now be boosted by switching from a forklift lumber picking process to that of a Lumber PickLine? That’s right, we have proven that a Lumber PickLine will boost the cutting output of all the major automated linear saws out there,... Read More August 2023 Issue #15289 Page 46
Design Connections: At the Intersection of Reality and the Codes Geordie Secord 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... Read More August 2023 Issue #15289 Page 84
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...

Truss Design Value Comparison Tables David Conner Timber Products Inspection has compiled design value comparison tables for several popular species and species groups as a helpful tool for truss manufacturers to determine if a lumber grade and/or lumber species substitution satisfies the original truss design. The data used comes from the 2018... Read More April 2023 Issue #15285 Page 84
Glued Roof Trusses Tuomo Poutanen In my previous article, The Evolution of Glued Trussed Joists, in the August 2021 issue, I explain that glued trusses have potential in floors. The new G-joist has high resistance. The chord shear failure is eliminated as the web finger punches the chord. The web-chord glue area is big. The mean... Read More April 2023 Issue #15285 Page 94
