Are You a Clicker or a Stickler? Glenn Traylor The question posed in the title, “are you a clicker or a stickler,” encourages you to examine just how apt you are to “click through” the steps in front of you versus carefully reviewing each item. Moreover, you should ask – are people in my organization paying... Read More October 2026 Issue #18327 Page 19
Stacked Chords in Wood Trusses: Importance of Proper Connector Plate Placement MiTek Staff When the top or bottom chords of a truss are subjected to large forces, or when load application or hanger requirements necessitate a wider chord member, designers sometimes use stacked chord members, where two chord members are placed one above the other. [For images, See PDF or View in... Read More October 2026 Issue #18327 Page 150
Using the Bearings Dialog to Control Wind Loads on Bottom Chords John Teems, P.E. In Truss Studio™, the Bearings dialog does more than define where a truss is supported—it directly influences how loads are generated, particularly wind loads on the bottom chord. Adjusting bearing location or type can change how the software interprets exposed versus supported... Read More October 2026 Issue #18327 Page 158
What are the Benefits of QA and Safety Audits? Glenn Traylor The term “audit” generally induces visions of tax audits. You imagine endless questions and boxes of records, as you attempt to produce documentation to defend what you’ve done. Importantly though, these visions are not what should come to mind when you think of a quality... Read More August 2026 Issue #18325 Page 19
ANSI/TPI 1-2022 – Person Load in MiTek Engineering Software MiTek Staff 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...

Does Your Plant Understand “Qualifying” the Lumber Used? Glenn Traylor Purchasing the correct grade of lumber to match your design drawing requirements is only one step in selecting the right lumber. Previously, we’ve discussed lumber quality in “Who is Responsible for Lumber Quality in Your Trusses?,” but let’s expand that discussion with... Read More June 2026 Issue #18323 Page 19
Do You Know That Plate Rotation has a Significant Impact on Load Transfer? Glenn Traylor and Donna Marino Our industry design standard, ANSI/TPI 1, regulates numerous elements in constructing roof and floor trusses. The following is a brief non-exhaustive summary: Lumber grades and moisture content Pedigree of lumber grades and lumber management Controls on truss profiles Verification of...

Interpreting the Snow Load Thermal Factor Frank Woeste and Marvin Strzyzewski When given a truss design project, the Truss Designer needs all of the loading parameters before starting work on it. This article will specifically discuss the Thermal Factor (Ct), which is part of the snow load calculations. As with any load parameter, using the wrong value will result in a...

Lumber Substitutions in Trusses Marvin Strzyzewski, P.E. Chapter 3 of ANSI/TPI 1-2022, the National Design Standard for Metal Plate Connected Wood Trusses, provides the component manufacturer with the Quality Criteria they must follow to ensure the metal plate connected wood trusses (MPCWT) they build meet the design assumptions. Section 3.4.2 Lumber... Read More March 2026 Issue #18320 Page 130
Should Roof and Floor Truss Ends Be Marked By the CM? Glenn Traylor Quality Assurance continues beyond the truss plant, so it’s important to keep that in mind as you’re preparing your products for handling and use by someone else. For example, this article poses the question: should component manufacturers (CMs) mark the ends of trusses? For that... Read More February 2026 Issue #18319 Page 19
