Design Connections: Design: Software Power or Brain Power? Geordie Secord I sometimes wonder if I am at risk of becoming the truss designer version of the grouchy old man that sits on the front porch yelling at the neighborhood kids to “get off my lawn.” When I hear some newer designer criticize the limitations of today’s truss layout and design...

The Development of the Truss Plate, Part I: The Perfect Storm Joe Kannapell, PE A nearly perfect confluence of circumstances combined to create the truss plate in South Florida. The wartime home-building hiatus, the post-war baby boom, and the northward (from Cuba) and southward (snowbird) migration to Florida all combined to skyrocket the demand for new housing. But what...

The Last Word: The Last Word on the Promise of Robotics Joe Kannapell, PE When $20 Billion behemoth Builders First Source (BFS) launched a robotic truss line in April, CMs were surprised that they would select House of Design (HoD)’s first truss machine, and the industry’s first robotic floor truss line. Remarkably, after just over 3 months, they’ve... Read More August 2022 Issue #14277 Page 134
The Development of the Truss Plate: The Split-Ring Connectors Prequel Joe Kannapell, PE For most of history, wood structures had been constrained by their connections. Nailed or bolted joints could only carry about half of what the wood could. As a result, our most abundant natural resource went mainly into homebuilding, where spans were short and stresses were low. That began to... Read More July 2022 Issue #14276 Page 10
Design Department Capacity Tracy Roe With component lead times being extremely long in our industry today, every manufacturer is scrambling to increase capacity. Some need more space, some need additional equipment, some simply need a labor force that is willing to work all day every day. Mostly, these needs can be met with capital...

The Last Word: The Last Word on the Robotics Transition Joe Kannapell, PE Robotics showed new promise for many CMs on May 17, ironically, by borrowing from the past 60 years of truss machinery. Attendees at SBCA’s Open Quarterly Meeting in Williamsburg, VA saw video of robots feeding truss parts into auto-jigging at the plant of their largest competitor,...

Sixty Years of Machines, Part XXXI: Icing on the Cake Joe Kannapell, PE In the year 2000, a transformation, like none other, gripped our industry. Jim Urmson’s TCT started it by breaking our component-saw-centric paradigm. Then in 2002, Dave McAdoo’s ALS quickened its pace by adding the capability to cut every conceivable truss part. But even before his... Read More June 2022 Issue #14275 Page 10
Seamless Communication Tracy Roe We’ve heard the statement forever: communication is key. Communication lies at the core of every successful relationship, team, and business. Our industry remains extremely strong and demand for metal plate connected wood trusses is as high as ever. Oftentimes when demand gets high and we... Read More June 2022 Issue #14275 Page 46
Checking Trusses at Bearing Locations for Out-of-Plane Buckling David Rothweiler and Bruce Feldmann Every truss design is evaluated for numerous criteria to determine if it is structurally sound. One of those checks is the capacity of the truss to resist buckling at a bearing location. This article focuses on checking out-of-plane buckling when a truss member is loaded in compression...

The Last Word: The Last Word on Sixty Years of Machines Joe Kannapell, PE From the quirky advance of truss machinery described in my Sixty Years of Machines series, one might conclude that we’re a quirky industry. We may be, but innovation in truss manufacturing is no different than advancement in U.S. industry in general. And, in fact, we are the epitome of... Read More June 2022 Issue #14275 Page 142
