As the building and construction industry continues to evolve, we strive to enhance and improve our understanding of the loads and conditions that we need to design for, the engineering tools and methods that we use in our analyses, and the materials with which we build. This advancement in our...

Every project begins the same way: a set of plans, a stack of details, and thousands of decisions waiting to be made. Somewhere between the architect’s vision and the completed structure lies a process filled with interpretation, calculation, coordination, and estimation. For decades,...

Per ANSI/TPI 1-2022 (National Design Standard for Metal Plate Connected Wood Truss Construction), Section 6.2.2.5, trusses with an overall span of 18 ft or greater must be evaluated for a 300 lb concentrated person load applied at the midpoint of any chord panel that is not sheathed with...

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...

Inspirado por las frecuentes solicitudes de una referencia rápida, he creado una hoja única de la guía del Capítulo 3 de ANSI/TPI 1, similar a una versión de CliffsNotes del estándar. Tenga en cuenta que se omiten detalles importantes; para una comprensión completa, consulte el estándar...

Inspired by frequent requests for a quick reference, I’ve created a single-sheet ANSI/TPI 1 Chapter 3 guide—similar to a CliffsNotes version of the standard. Please note that important details are omitted; for a complete understanding, consult the full standard, National Design...

While attending an Ontario Structural Wood Association meeting in October – somewhat like attending an SBCA Chapter meeting – part of the discussion turned to the quality of house plans. After many years in this industry, I can tell you that this discussion wouldn’t have...

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...

Imagine a looming deadline, a complicated 2D, multi-family floor plan. It will take days to get accurate measurements, manually. STITCHER® streamlines the process by capturing walls, openings, and intricate details with precision, transforming a 2D architectural drawing into a 3D model in a...

Metal plate connected roof and floor trusses are used widely in residential single family, multi- family, commercial, and agricultural construction. They provide design flexibility, span greater distances than traditional “stick framing,” and allow faster erection of the roof system...
