As this issue of The Advertiser is being published December 1st, I thought I would share my wish list for truss and component manufacturers this year. Feel free to use this in your letter to Santa, too! Dear Santa, I promise I tried to be a good component designer this past year. My...

Oftentimes, MiTek engineers are getting requests for repairs of trusses installed out of plumb. This is a common installation issue and has some allowable tolerances. Tolerance is critical for both a good roofline and effective bracing. Exceeded erection tolerance can cause overloading,...

Metal plate connected roof and floor trusses are used widely in residential single family, multi- family, commercial, and agricultural construction. They provide design flexibility, span greater distances than traditional “stick framing,” and allow faster erection of the roof system...

MiTek engineers are often asked what maximum gaps are allowed for wood member-to-wood member in metal-plate-connected wood trusses. Gaps between wood members are addressed in Chapter 3 Quality Criteria for the Manufacture of Metal-Plate-Connected Wood Trusses of the ANSI/TPI 1-2014 (National...

Prior to joining Simpson Strong-Tie, I spent 13 years working as consulting structural engineer. As a specifier, I was amazed at the number of resources Simpson made available to me. From software, to blogs, to design guides, there were many resources to help me solve problems and streamline the...

My favorite place to meet with a customer is on the job site. Always has been. I started in this industry approximately 20 years ago as a young truss salesman for UFP in Southern California. My training consisted of building trusses in the yard, creating estimates, and completing engineering...

The National Design Standard for Metal Plate Connected Wood Truss Construction, ANSI/TPI 1-2022 has been updated to require a design load check that accounts for a Person Loading of a roof truss chord without structural wood sheathing. As discussed in the ANSI/TPI 1 Commentary, this loading...

As the current lab manager of the newly renamed Karen Colonias Research Laboratory, I’m proud to share what our lab does and what Karen meant to us. Our lab is responsible for testing new and existing connector, fastener and Truss plate products in support of our product development...

Top chords are usually braced by roof sheathing. Roof sheathing provides effective lateral bracing when nailed directly to the top chord. In cases where roof sheathing cannot be directly applied to the top chord, purlins are used to prevent lateral buckling of truss top chords. The Truss...

MiTek Engineering software gives you two options to input snow load – Ground Snow and Roof Snow (flat roof snow). What is the difference between ground snow and flat roof snow? Ground snow load, pg, is obtained directly from the American Society of Civil Engineers Standard (ASCE 7)...
