Design Connections: Estimating and the Cost of Quotes Geordie Secord One constant thorn in the side of truss fabricators is the cost of preparing quotes, often multiple times for the same job through the life of a project. I find that this is especially true for custom homes, as they often go through numerous revisions for aesthetic, budget, zoning, and other... Read More July 2024 Issue #16300 Page 90
Am I Allowed to Move a Truss If There are Obstructions? MiTek Staff Typically, trusses are spaced evenly. The spacing shown on MiTek engineering drawings is a tributary area carried by the trusses. Each truss is designed to support one-half of the roof/floor load on each side. The spacing between the trusses may be of any combination if the tributary area does...

Wall Panel Technology, Part II: Panel Equipment Proliferates Joe Kannapell The demand for wall panel equipment after World War II was unprecedented, even to this day. Industrialization was in the air, and factory-built wall panels became the gateway, even before roof trusses. Most of the action was in the affordable housing sector, driven by the mobile home, modular,... Read More May 2024 Issue #16298 Page 10
Enhancing Truss Build Efficiency Edmond Lim, P.Eng. Enhancing truss builder efficiency will increase productivity and result in more truss production at lower cost. The most cost-effective way of enhancing truss builder efficiency is to put TVs up over each truss jig as a visual truss assembly aid. Enventek PlantOne TV/Projection is compatible...

Design Connections: Resilient Designs Cost Less Than You Think Geordie Secord In last month’s article, Designing for Resiliency, I present some of my thoughts on how changing the design approach for wood trusses could aid in making future homes more resilient to the types of climate extremes that seem to be ahead of us. Whether you think that climate change is a... Read More April 2024 Issue #16297 Page 86
Wood Member-To-Wood Member Gaps MiTek Staff MiTek engineers are often asked what maximum gaps are allowed for wood member-to-wood member in metal-plate-connected wood trusses. Gaps between wood members are addressed in Chapter 3 Quality Criteria for the Manufacture of Metal-Plate-Connected Wood Trusses of the ANSI/TPI 1-2014 (National...

Should We Seal All Engineered Drawings? Glenn Traylor Recently, while conducting an ANSI/TPI audit, a splice caught my eye. When I investigated further, I realized that the bottom chord of the truss I was investigating had a very short, 2” chord segment. I immediately assumed the truss builders had cut a short block to make up for a miss-cut... Read More May 2023 Issue #15286 Page 37
Design Connections: Is There Ever Just One Right Way? Geordie Secord 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... Read More March 2023 Issue #15284 Page 80
Understanding Plate Tooth Count and Placement Russell Tangren, PE Imagine a third-party truss inspector is in the yard checking truss plates as part of quality control. The plate placement diagram indicates the web needs twenty-five teeth; however, the inspector counts twenty. Even though the shop positioned the plates as designed, is the plate placement...
