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...

One unique thing about our industry is the diversity among markets across the country. The upper Midwest does things very differently than the South. The methods used in the West don’t align with the those used in the East. None are wrong, but most are very different. At their core, each...

Visual tools are essential throughout the different phases of design and construction. Today, 3D models play a major role in construction projects, as they help improve productivity. Component manufacturing is no exception. The 3D Viewer Tool was developed and modernized to help component...

Today’s technology has made life easier for the truss designer and others in the truss fabrication process. In the early days of the truss industry, we used, reused, and modified existing designs to create new designs using paper, pencil, and a handy Smoley’s Book. Soon we graduated...

As one of the top 10 private homebuilders in the US (and one of the top 25 overall), Gehan Homes has explored its fair share of technologies promising efficiency and productivity gains. When it came to pulling home designs, plans, elevations, and options into full job start packets (JSPs), the...

A Truss Design Drawing (TDD) includes specific information[1] for structural engineers and building designers: truss profile, plates, loadings, wind speed, codes, enclosure, exposure, reactions, deflections, materials, bracing, bearings, etc. The maximum reactions are the most important values...

In the last few years, Simpson Strong-Tie has heard from a number of structural engineers expressing frustration with the lack of performance data for shallowly embedded, post-installed anchors (shallow anchors). Engineers of Record (EOR) have identified a common application for shallow anchors...

It’s a simple fact—successful projects depend on good communication. What’s not so simple—there’s a tremendous volume of information that must be shared between multiple stakeholders in any construction project. Last month’s article, The 3D Model Everyone Can...

I-joists dominate the joist market due to their high material efficiency and low manufacturing cost. However, this product has disadvantages, including difficulty in HVAC installations and the possibility of bottom chord support only. Therefore, the market would pay a considerable premium for a...

With the economy in the United States on the rebound, truss designers are in unusually high demand. Unlike other professionals in the building industry, a truss designer is not required (at present) to have any formal education or any type of college degree. Fact is, there is presently nowhere...
