Thus, Specifying an anchor that lacks a current qualification report to ACI 355.4-19 means your concrete anchorage design is code-noncompliant.

ACI 355.4-19 covers a wide range of topics related to post-installed anchors in concrete, including:

In the world of structural engineering and construction, the phrase “tested to code” carries immense weight. When it comes to anchoring into concrete, the safety of an entire structure can depend on a single fastener. For decades, the industry has relied on a patchwork of testing standards to validate post-installed adhesive anchors. However, that landscape changed significantly with the introduction of ACI 355.4-19. aci 355.4-19 pdf

It covers any organic or inorganic adhesive used with steel elements (threaded rods, rebar) in concrete. It does not cover mechanical expansion anchors (those fall under ACI 355.2).

is the official standard titled “Qualification of Post-Installed Adhesive Anchors in Concrete and Commentary.” It was published by the American Concrete Institute (ACI) in 2019, superseding the previous 2011 version (ACI 355.4-11). Thus, Specifying an anchor that lacks a current

ACI 355.4-19 is a standard published by the American Concrete Institute that outlines the requirements for the qualification of post-installed anchors in concrete. The document provides guidelines for the testing and evaluation of anchors used in concrete construction, ensuring that they meet the necessary safety and performance standards.

“Provide third-party test reports demonstrating compliance of the proposed adhesive anchor system with ACI 355.4-19, dated 2019, including Section 6 (Sustained Tension Tests) and Section 9 (Seismic Tests) where applicable.” For decades, the industry has relied on a

Seismic design categories C through F require anchors to withstand cyclic loading. ACI 355.4-19 refined the displacement limits and cycling protocols to better simulate earthquake-induced forces. Anchors qualified under the 2011 version may no longer be assumed to meet the 2019 seismic requirements.
