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...

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....

A test lab is a building product manufacturer’s one-stop shop for engineering, manufacturing quality, and performance verification. Whether supporting new product development, regulatory submissions, or customer assurance testing, a test lab must have the right tools to get the job done....

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’...

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...

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...

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...

How much time should you invest in learning about your business, and what are the best methods for training? You may not realize it, but our annual industry tradeshow is one of the best places to combine multiple objectives including valuable learning opportunities. Each year, component...

A Repetitive Member Increase (Cr) in truss design accounts for the load-sharing and composite action that occurs when multiple members, connected by load-distributing elements, act together as a system. This is an adjustment to allowable stresses of multiple members (like trusses, joists,...

A recent phone call has prompted me to address the issue of fixing gaps. There are some misunderstandings about what qualifies as a member-to-member gap, and the options to fix them are not always clear either. ANSI/TPI 1 recommends that members in a truss to touch each other when possible....
