Overview of the Strength-Based Cracked and Uncracked Masonry Design Standards for Adhesive Anchors

We’re entering the year 2024 — welcome to the world of cracked and uncracked masonry. The last time Simpson Strong-Tie wrote a blog post regarding design criteria for post-installed anchors in masonry was in 2019, and ICC-ES was considering the adoption of a revised version of AC58, the Acceptance Criteria for Adhesive Anchors in Cracked and Uncracked Masonry Elements. Acceptance Criteria, or ACs, outline the testing that a manufacturer must comply with in order to get an evaluation report. In some cases, the ACs contain calculations methods if they are otherwise unavailable. If you missed the previous blog post, here is a link so you can explore a bit of the history that has led us to where we are today.

Introducing AT-3G™: Your high-strength cold-weather, fast-cure anchoring adhesive

In general, postinstalled adhesive anchor design per ACI 318 Chapter 17 is relatively straightforward. In practice, however, postinstalled anchorage can often become challenging because of fasttrack project schedules, supply issues, ever-changing weather conditions, design conflicts/changes, or unexpected field conditions.

Three Ways Anchor Designer™ v3.0 Simplifies Design

Since the introduction of strength design for post-installed anchors in IBC 2000, determining the designed capacity of anchors has become increasingly complex. Dozens of variables, such as geometry, concrete conditions, and the specific properties of different anchor types, make a quick, straightforward comparison of design options almost impossible. Leaving behind printed tables and digital spreadsheets, many manufacturers now offer software to simplify anchor design and provide design feedback in real time. Simpson Strong-Tie offers Anchor Designer software to specifiers as a free, intuitive design tool that streamlines the anchor design process.

How Should I Determine a Tension Test Load? Guidelines on Proof Loading Adhesive Anchors

Have you ever been involved on a project where a post-installed anchor failed when loaded? What was the circumstance? Was the anchor installed with incorrect torque or was the hole improperly cleaned, resulting in lower capacities than published? Unfortunately, in the world of concrete anchors, installations are sometimes incorrect as a result of not following instructions. Alternatively, perhaps you’re working on a project where special inspection wasn’t performed as required by the building code. What should be done in these cases?
