Moment connections are a common lateral system in structural steel design, offering the advantage of unobstructed sight lines and clear passageways. However, they often come with significant cost and labor demands. Fully welded moment connections require extensive beam preparation, welding, and inspection, while common bolted solutions, such as flange-plated and end-plate moment connections, still involve welded components, leading to installation and fit-up challenges.

Framing the Future: The Evolution of Moment Frames
Discover insights from Simpson Strong-Tie engineer Emily Morris Frazier, P.E., as she examines the evolution of moment frame construction over the past 150 years. She traces the transition from early rivet and angle connections to the prevalent use of welded moment frames in seismic zones. Emily addresses the challenges that emerged after significant earthquakes, which spurred the development of prequalified connections to boost safety and performance. She highlights the ongoing advancements in design strategies that aim to enhance the resilience of modern structures.

Using the Edge-Tie™ System to Create Curved Façades in Steel Construction
Curved façades can help create architecturally appealing steel structures and may even reduce the effects of wind loading. However, careful coordination is needed between engineers, contractors and glaziers when locating façade attachments. Providing adequate tolerances and avoiding field fixes can prove to be more challenging for curved façades than for conventional rectangular ones.
Introducing AT-3G™: Your high-strength cold-weather, fast-cure anchoring adhesive
In general, post–installed adhesive anchor design per ACI 318 Chapter 17 is relatively straightforward. In practice, however, post–installed anchorage can often become challenging because of fast–track project schedules, supply issues, ever-changing weather conditions, design conflicts/changes, or unexpected field conditions.
Simpson Strong-Tie® Yield-Link® Moment Connection Case Study: Rose Avenue Elementary
Structural engineers for the Rose Avenue Elementary School project in Oxnard, California, a high seismic zone, chose to switch from special moment frames requiring welded connections to the Simpson Strong-Tie Yield-Link moment connection, which features bolted connections instead of onsite welding. This case study shares the experiences of structural engineers, fabricators and other project partners utilizing this innovative solution for structural steel construction.
Common Engineering Technical Inquiries — Part I: Anchors
Over the next few months, I will be doing a short three-part series going over common technical inquiries we receive in the engineering department. There is a wealth of information available on our website and in our literature, but so much content can sometimes be difficult to navigate. It is often said that knowledge is power, so my hope is to empower you with all the technical support you need so you can complete your job quickly and efficiently.
Mechanical Anchors: Screw vs. Expansion: — Which Is Right for Me?
Not all post-installed mechanical anchors are created equal. There are key differences between screw and expansion anchor types — differences that include how they gain their holding strength, installation requirements, and overall anchor performance. In the following post, field engineers Todd Hamilton, Chris Johnson and Derek Gilbert compare the two anchor types.
Spotlighting Our Yield-Link® Moment Connection: Three Project Cases
Our Yield-Link connection is precision-made to meet the tough demands and increased loads of structural steel construction. From building owners to engineers, to contractors and fabricators, the Yield-Link’s state-of-the-art design saves everyone time and money — while providing a connection that keeps structural steel buildings strong and safe.
How a Top US Homebuilder Turbocharged Market Growth and Managed the Job Start Process with the Scalable LotSpec Solution from Simpson Strong-Tie
As one of the top 10 private homebuilders in the US (and one of the top 25 overall), Gehan Homes has explored its fair share of technologies promising efficiency and productivity gains. When it came to pulling home designs, plans, elevations, and options into full job start packets (JSPs), the Texas-based homebuilder managed to generate about 400 JSPs per year before the productivity cost of eight hours each began to limit growth.
