Frame and truss machinery has always competed on mechanical engineering design, and it still does. But, when you ask a plant manager where the day-to-day pain and gains in their plant actually come from, increasingly the answer is software. Throughput, uptime, operator experience — these...

Perhaps you’ve seen our company name or maybe you’ve watched my episode of The Common Chord by Paragon, People First Innovation in Truss Design. But if we haven’t met, let me introduce myself. I’m Jarred Frescura, Managing Partner and Director of Design Services for...

Designing long-span trusses starts with a clear definition. Establishing what constitutes a long-span truss sets expectations early, helping to drive smarter design, manufacturing, and logistics decisions from the outset. [For all figures, See PDF or View in Full Issue.] Defining Long-Span...

Mansard-type trusses are a type of roof truss that extend outward and are supported only on top and bottom of the tall end, allowing it to cantilever out without additional support. [For all images, See PDF or View in Full Issue.] They are commonly designed with a pin and vertical roller...

I had a chance not long ago to grab coffee with an old college roommate. We’re both engineers by trade, but our careers took different paths — he went into structural consulting, while I went into component design, working with wood trusses. As often happens, the conversation quickly...

Sometimes, a designed and engineered connection will appear to look like a member to member gap. Because of that, we need to ask the question: should the truss designer always try to eliminate a member to member gap in a truss? Generally speaking, yes, it’s always worthwhile, but there are...

A chase is an intentional opening in a floor truss created by omitting specific diagonal webs to provide space for HVAC ducts, plumbing lines, or electrical runs. For structural efficiency, chases should be located within the middle third of the truss span, where shear forces are lowest....

The “Inspect” tool in Plate Monitor (Joint Properties) is a little known and certainly underutilized tool in the Truss Studio design software that can help you quickly deal with joint plating changes and issues. [For all images, See PDF or View in Full Issue.] We developed this tool...

Wood was not held in high regard in the truss drafting department where I began working. Our fabricator customers often wanted their trusses designed with “old lumber,” meaning the obsolete size of 1-5/8” x 3-5/8”, even though the 1.5” x 3.5” size had been in...

Our industry design standard, ANSI/TPI 1, regulates numerous elements in constructing roof and floor trusses. The following is a brief non-exhaustive summary: Lumber grades and moisture content Pedigree of lumber grades and lumber management Controls on truss profiles Verification of...
