Information Needed to Provide Efficient Truss Design Repairs MiTek Staff Metal plate connected roof and floor trusses are used widely in residential single family, multi- family, commercial, and agricultural construction. They provide design flexibility, span greater distances than traditional “stick framing,” and allow faster erection of the roof system... Read More November 2023 Issue #15292 Page 97
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,...

The Last Word: Can Crooked Lumber Defeat Robotics? Joe Kannapell 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...
