Qualification of Post-Installed Adhesive Anchors (Chapter 7) (PDF)

Pdf Summary

The document titled "Qualification of Post-Installed Adhesive Anchors in Concrete (ACI 355.4-11) and Commentary" is a standard produced by the American Concrete Institute ACI Committee 355. Published in August 2011, this standard prescribes testing protocols and evaluation criteria for post-installed adhesive anchors in concrete, ensuring their use under the design guidelines of ACI 318. It addresses the performance of these anchors in both uncracked and cracked concrete and provides comprehensive assessments for variable conditions like seismic loading, environmental factors, and temperature variations. <br /><br />The document provides guidelines for establishing characteristics such as bond strength and various design parameters, specifically for concrete constructions, with the aim to enhance structural anchorage reliability. Notably, it includes mandatory testing for the acceptance in both uncracked and cracked concretes, emphasizing conditions such as cracked concrete, aggressive environments, reduced/elevated temperatures, and serviceability during seismic events. It includes assessments for both bond strength and system categorization alongside quality control mandates and addresses health and safety practices.<br /><br />Contents are organized into various chapters, including introductory topics, general requirements, assessments of anchor elements, testing criteria, and data presentation, all structured to help users apply the document effectively in their respective concrete anchoring projects. <br /><br />Additionally, this standard serves as part of a safety assurance and quality control methodology, assisting practitioners in verifying that anchored systems meet mandatory performance and reliability requirements, including provisions for correct installation and use against long-term stresses like freeze-thaw cycles and sustained loading. <br /><br />ACI 355.4-11 supersedes its provisional predecessor ACI 355.4-10, and it directs users to periodically check for errata to maintain up-to-date compliance with technical advancements or corrections.
