Last month’s article, “The Designer Shortage—Where Can We Find Them?”, offered some suggestions for finding new component designers. This month, I have some suggestions for training those new hires effectively. And bear in mind, as I mentioned last month, I think it is...

When designing trusses for special loads or special conditions, it is important to define the individual truss members correctly. Without proper member definitions, trusses could be inadvertently under-designed and/or have incorrect analog. The most common member types are webs and chords. Top...

Among our industry’s unsung heroes, Walter Moehlenpah takes a close second place behind Cal Jureit. Both built pivotal, pioneering businesses, Jureit through his truss plate and Moehlenpah through his truss machine. Yet Jureit was bound to have the upper hand, as he was the truss...

A challenge for the component industry is brewing no matter if you are located in an area where new home construction continues to be strong or your market is slowed by the combined effects of high interest rates and stubbornly high inflation. Be it single family or multi-family, new designers...

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...

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...

Trusses are designed as individual components to resist the in-plane stresses resulting from the loads applied in the same in-plane direction. To resist out of plane forces, adequate bracing/restraint is required. In absence of designed temporary and permanent bracing plans, BCSI (Building...

As builders began demanding Gang-Nailed trusses, imitators answered their call with little concern for violating Cal Jureit’s patent. Even though his claims were technical triumphs, vetted by D.C. patent experts, they were quickly contested by two now-familiar figures, Bill Black and...

If you have spent your truss career in one region, and even more so with just one company, you will have seen that, generally speaking, your competitors and co-workers tend to frame houses essentially the same way. Only when you are exposed to a different company or region do you start to see...

Attic truss with 7 feet room height – should it be designed for 20 psf (pounds per square foot), 30 psf or 40 psf room live load? IRC (International Residential Code) defines Habitable Space as a space in a building for living, sleeping, eating, or cooking. Per IRC 2018 Table...
