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.
