The Yield-Link brace connection (YLBC) from Simpson Strong-Tie is an innovative solution for isolating damage to ensure that braced frames within structural steel buildings remain intact during a seismic or wind event. With predesigned, bolted connections, the YLBC simplifies design work, eliminates the need for field welding, and is easy to incorporate into new builds or retrofits.
Learn New Design Methods to Enclose Buildings Faster Webinar Q&A
In this post, we follow up on our October webinar, New Design Methods to Enclose Buildings Faster, by answering some of the interesting questions raised by attendees.
During the webinar, we discussed new design methods and solutions for curtain-wall and cladding connections and how they can maximize efficiency and resiliency throughout the construction process.

Building Stronger Stick-Frame Roofs: Code Requirements and Connection Solutions
While stick-frame roofs are sometimes preferred to premanufactured roof trusses in some areas of the country because they can accommodate larger attics, higher ceilings, and complex roof shapes, the code requirements for these roofs are often more complex. That’s largely because, unlike truss-framed roofs, the code needs to provide a complete prescriptive method of building the roof, including the multitude of connections that must be made in the field. And, to complicate matters further, the code requirements for stick-frame roofing have been rewritten in each of the last two code cycles. I’d like to give you a high-level overview of some of those changes. In a previous SE Blog post, we discussed the design concepts of stick-framed roofs, and summarized a few of the solutions offered by the Simpson Strong-Tie® connector system for stick-frame roofing. The main concept in that post was the necessity of a continuous tie across the bottom of the rafter system to prevent the heels of the rafters from spreading under load and pushing out on the tops of the walls.
Questions Answered: Yield-Link® Connection for Steel Construction
In this post, we follow up on our May 2 webinar, Seismic Resilience and Risk Assessment of the Yield-Link® Connection for Steel Construction, by answering some of the interesting questions raised by the attendees.
During the webinar, we discussed how to achieve seismic resiliency in steel construction with our Yield-Link connection for steel special moment frames and the Seismic Performance Prediction Program (SP3) by Haselton Baker Risk Group. In case you weren’t able to join our discussion, you can watch the on-demand webinar and earn PDHs and CEUs here.
As with our previous webinars, we ended with a Q&A session for the attendees. Jeff Ellis, our Director of Codes and Compliance, and Curt Haselton and Jared Debock, from Haselton Baker Risk Group, answered as many questions as they could in the time allowed. Now we are back to recap some of the more commonly asked questions and their answers. If you’re interested in seeing the full list of questions, click here.
Questions Answered: Strong-Wall® Site-Built Portal Frame System
In this post, we follow up on our April 17 webinar, Meeting Braced-Wall Requirements: A New Portal Frame Solution, by answering some of the interesting questions raised by attendees.
During the webinar, we discussed how the Strong-Wall site-built portal frame system (PFS) provides designers, builders and contractors in prescriptive jurisdictions with a new alternative to IRC wall-bracing methods.

Upgrade Your Coiled Strap: How an Innovative Embossment Takes Utility Straps to the Next Level
CS16 coiled straps. I can’t tell you how many thousands (maybe more) I specified during my time as a consulting engineer. Straps are used everywhere. They were then, and are now, a go-to solution for drag and uplift loads. I didn’t have to look them up in the catalog — I knew the allowable loads by heart.
Then one day at a jobsite, I saw a contractor installing them and thought, “Wow, that is labor intensive. His arm must be so tired!” Suddenly, I felt a little guilty for all of the straps I had personally specified on my projects. I thought there must be a better way. Fast-forward 10 years, and today I’m an R&D engineer for Simpson Strong-Tie, an industry leader that prides itself on offering products that improve construction, keep costs down and allow for a safer built environment. As fate would have it, straps fall into my area of responsibility. Now, thinking about what could be done to improve a flat, steel strap is part of my job. Specifiers use straps load rated based on a National Design Specification® (NDS®) nail calculation and an American Iron and Steel Institute (AISI) steel calculation. How could Simpson Strong-Tie make that better?
Questions Answered: Making the Right Anchor Choice
In this post, we follow up on our August 28 webinar, Making the Right Anchor Choice: Best Practices in Anchor Design, by answering some of the interesting questions raised by attendees.
During the webinar where we discussed the critical performance factors and code requirements you need to consider when designing with or installing adhesive or mechanical anchors. In case you weren’t able to join our discussion, you can watch the on-demand webinar and earn PDH and CEU credits here.
Drive a New Path: Resisting Uplift with Structural Fasteners
Structural screws are designed and tested to do hard work, but that doesn’t make them hard to use. In this post, Simpson Strong-Tie structural engineer Bryan Wert explains how the load-rated strength, versatility and easy installation of the code-listed Strong-Drive® SDWC Truss screw and SDWF Floor-to-Floor screw make it a cinch to create a continuous load path to resist wind uplift.
Winter’s finally shedding her blanket and unveiling springtime in Texas. There’s now a short window of picture-perfect weather where my purchases at Home Depot are no longer foam hose bib covers to protect outdoor faucets from freezing temperature, but aren’t quite yet tiki torches and floats for the pool for hot and humid summer days. I find myself in the garden center looking at the freshly delivered trees, shrubs and flowers, along with just about every other adult in my city. This year, my wife’s decided we need to surround our outdoor living space with hanging planters displaying perky red, purple, yellow and blue flowers.

A New Way to See Whether FRP Is Right for Your Project
Specifying our Composite Strengthening Systems™ (CSS) is unlike choosing any other product we offer. In light of the unique variables involved with selecting and using fiber-reinforced polymer (FRP) solutions, we encourage you to leverage our expertise to help with your FRP strengthening designs. To get started, we first need to determine whether FRP is right for your project. The fastest way to do that is for you to fill out our FRP Design Questionnaire. Our new Excel-based questionnaire collects your project information and helps you use the existing capacity check to evaluate whether or not FRP is suitable for your project per the requirements of ACI 562-16 Section 5.5.2. After the feasibility study, the questionnaire creates input sheets specifically for your project.
