For the first time in U.S. model building code history, tornado design provisions for Risk Category III and IV buildings are given in the 2024 IBC. In fact, John ‘Buddy’ Showalter and Sandra Hyde have an excellent article on this, “2024 IBC Significant Structural Changes...

In early November, the Truss Plate Institute (TPI) was proud to announce the launch of our two new ANSI standards projects: TPI 2 – National Standard for Testing Metal Plate Connected Wood Trusses and TPI 3 – National Design Standard for Bracing Metal Plate Connected Wood Trusses....

We enjoyed a productive week at BCMC in Omaha, strengthening relationships and renewing our commitment to the truss industry, and we hope you can say the same! Timber Products Inspection (TP) returned with our popular ANSI/TPI 1 Chapter 3 challenge truss, designed to test participants’...

Joist hangers are simple to install, but ignoring details can cause issues with inspectors and lead to project delays. At our office, we often see the same mistakes repeated—simple errors that are easy to avoid with proper care and following best practices. Here are the five most common...

What is an extended top chord bearing truss? For those who don’t see these types of trusses on a daily basis, an extended top chord bearing truss is simply that which contains a top chord extension or tail supported by a bearing. This tail can then bear on a wall, beam, another truss, or...

In multiple jurisdictions across the country, building code authorities questioned the viability of the curiously shaped metal plates being used on trusses during the last half of the 1950s. In South Florida, for example, four radically different looking plates appeared, with different...

Still defaulting to rim boards at every floor edge? In modern wood-framed construction, it’s worth taking a closer look at several detailing options including ribbon boards or top chord bearing detailing. These options can simplify construction and reduce blocking material while still...

MiTek engineers frequently receive questions on why the note “Solid blocking is required on both sides of the truss at joints…” appears on an engineering drawing and how to address it. This often arises at the high heel joints. [For all images, See PDF or View in Full...

Cal Jureit’s truss testing experience was but the first of three consequential steps that led him to invent the modern truss connector plate. Jureit’s second step was joining Truss Fabrications, Inc. (TFI), which furthered his knowledge of truss manufacturing, and focused his efforts...

The ANSI/TPI 1 standard is a critical document that governs the design and quality criteria for metal plate-connected (MPC) wood trusses. It serves as a guideline for truss manufacturers and engineers alike, providing the technical framework to design and construct reliable and code-compliant...
