The anchorage of nonstructural components like mechanical and electrical equipment is an important element of ensuring life safety that doesn’t always get the same attention as the structural engineering required for the building itself. The key standard that governs design loads is ASCE 7. This blog post explores updated equations in the newest edition of the standard, ASCE 7-22, specifically Chapter 13, which covers seismic design of nonstructural components. We’ll walk step by step through an example of anchoring a piece of equipment to a concrete slab inside a Risk Category IV building in a high seismic area.

Anchor Anatomy 101: Drop-In Internally Threaded Anchors
This is the fifth Anchor Anatomy 101 blog post focusing on anchor systems. Each post is designed to clarify anchor components, installation processes, and common applications to help you make informed anchor selection decisions based on your project’s unique requirements. Our preceding post focused on the Heli-Tie™ helical wall tie. This post reviews a few types of drop-in internally threaded anchors.
PAF, GAF or Pass? Part 2: Acceptable Uses and Limitations for Power-Actuated Fasteners in Seismic Applications
In Part 1 of this two-part series, we discussed how power-actuated fasteners work, the varying load strengths, the similarities and differences between powder-actuated and gas–actuated tools and pins, and the approval process for Evaluation Reports. Now that we have a basic understanding of pins and power–actuated tools (PATs), we are ready to dive into the acceptable uses for these fastening systems and specific limitations that exist as they pertain to the resistance of seismic forces.
PAF, GAF or Pass? Part 1: A Guide to Selecting a Power-Actuated Fastening Solution
“PAF, GAF or Pass?” is a question that designers are often faced with when they need to attach wood or mechanical, electrical, or plumbing (MEP) fixtures to concrete, steel, or masonry structures, because there are several considerations to be made when deciding whether to utilize a direct-fastening solution or to “pass” and utilize a different attachment method. This is Part One of a two-part series discussing power–actuated fasteners and their applications. Before we get into the nitty-gritty, let’s define these acronyms and discuss how these types of fasteners work.
Anchor Anatomy 101: Heli-Tie™ Helical Wall Tie
This is the fourth Anchor Anatomy 101 blog post focusing on anchor systems. The goal of each post is to review anchor components, installation processes, and common applications to help you make informed anchor selection decisions based on your project’s unique requirements. The prior Anchor Anatomy 101 blog post focused on wedge type anchors. This blog post “drills down” into helical wall ties.

Unveiling the HDUE Holdown: Engineering Marvels and Rigorous Testing
The HDUE Holdown represents the latest milestone in a long history of innovative products at Simpson Strong-Tie. Our journey began in 1966 with the introduction of the first HD welded holdown, a robust, raw steel piece designed to secure posts to foundations (figure 1). Over the decades, we have continually refined and improved our designs to meet evolving industry needs and standards.
