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....

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...

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...

The International Code Council (ICC) recently completed the first of two Group B Code Action Hearings (CAH) in Orlando, Florida, from April 27 to May 6 for development of the 2027 I-Codes. The second CAH will be held in October in Cleveland, Ohio. This marks a significant milestone in the new...

Generally speaking, ANSI/TPI 1 makes common sense and is very logical. However, there are several items that can be a little confusing because they seem to defy logic. When we upgrade lumber per ANSI/TPI 1 Section 3.4.2, we know that lumber strength needs to be maintained in order to meet the...

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...

Managing a truss with multiple pieces can affect productivity. For example, maintaining compliance with ANSI/TPI 1 Chapter 3 requirements for nearly thirty pieces can be challenging. To improve cycle time while preserving quality, using sub-components may be a practical solution. Most likely,...

Product testing is the backbone of quality control in engineering and manufacturing, ensuring products are reliable, durable, and safe before reaching the market. Over the years, the testing processes have evolved dramatically, transitioning from manual inspections to highly sophisticated...
