ASCE 7-22 Shakes Things Up: Changes to Seismic Calculations for Anchorage of Equipment

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 itselfThe 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

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 gasactuated tools and pins, and the approval process for Evaluation Reports. Now that we have a basic understanding of pins and poweractuated 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 structuresbecause there are several considerations to be made when deciding whether to utilize a direct-fastening solution or to pass and utilize a different attachment methodThis is Part One of a two-part series discussing poweractuated fasteners and their applications. Before we get into the nitty-grittylet’s define these acronyms and discuss how these types of fasteners work.
