Bringing Innovation to the Forefront of the Construction Industry

MiTek Staff

Today’s construction industry is governed by a complex network of building codes and standards. In the U.S., the development cycle for new building codes spans three years, while the creation of new standards may take even longer. As a result, adoption and acceptance of innovative,...

Fastener Substitutions in Connectors — Where We Started and Where We Are

Paul McEntee

We often get questions about using fasteners different from those listed in a connector’s catalog load tables. A question came up recently, and I said, “I did a blog post about that not too long ago.” Turns out that blog post is over 10 years old, which no longer qualifies as...

How Will the Changes to ANSI/TPI 1 Impact Your Truss Builders and In-House Inspectors?

Glenn Traylor

As we migrate from ANSI/TPI 1-2014 to ANSI/TPI 1-2022, it is important to discuss and be aware of Chapter 3 updates. These changes impact QC inspections and should be understood by your in-house QC inspector and your truss builders. The changes are in two categories in Chapter 3 — a...

Striking Gold with Posi-Strut in Carson City

Landon Boucher

A large part of what MiTek’s Design Engagement team does involves meeting with Structural Engineers, Architects, and Real Estate Developers to advance the use of components. We guide them on best practices early in design so that when construction documents arrive at the truss...

Changes in Flat Roof Snow Calculation in ASCE 7-22

MiTek Staff

Chapter 7 of ASCE 7-22 (Minimum Design Loads and Associated Criteria for Buildings and Other Structures) introduces significant changes that affect the magnitude of snow loads and, consequently, truss design. While some of these changes reduce snow load values, others increase them. One of the...

Home Building Technology, Part VI: The Original Wood Truss Manufacturers

Joe Kannapell, PE

Although last month’s article in this series, “Home Building Technology, Part V: Early Truss Connection Innovators,” brought our story up to the post-war time period, we would be remiss without acknowledging the original truss manufacturers in greater detail. A small group of...

Home Building Technology, Part V: Early Truss Connection Innovators

Joe Kannapell, PE

Three midcentury forces converged to form the truss business we know today. First came the deluge of demand for affordable housing after World War II. Then came the prefabbers who addressed that need with trusses. And finally came the connector that made trusses into a blockbuster...

Multiple-Ply Girder Load Distribution Change in ANSI/TPI 1-2022

MiTek Staff

Girder trusses are trusses specially designed to carry extra load from tie-in trusses and equipment. If a single ply is insufficient to carry the entire load, the truss designer specifies a multiply girder, that is made of identical trusses and fastened together to act as one unit to support the...

Hand Calculations for Maximum Gravity Reaction on Truss Design Drawings

Alpine Team

Building engineers rely on maximum gravity reactions (R+) from Truss Design Drawings (TDD) to design structural components. These maximum reactions are calculated based on load combinations specified by building codes, representing the highest downward forces which allow engineers to determine...
