Qualification of Post-Installed Mechanical Anchors in Concrete
|Publication Date:||27 October 2004|
ACI 355.2 prescribes testing and evaluation requirements for post-installed mechanical anchors intended for use in concrete designed under the provisions of ACI 318. Criteria are prescribed to determine whether anchors are acceptable for use in uncracked concrete only, or in cracked as well as uncracked concrete. Criteria are prescribed to determine the performance category for each anchor. The anchor performance categories are used by ACI 318 to assign capacity reduction factors and other design parameters.
ACI 355.2 describes the tests required to qualify a post-installed mechanical anchor or anchor system for use under the provisions of ACI 318.
ACI 355.2 applies to post-installed mechanical anchors (torque-controlled expansion anchors, displacement-control
ACI 355.2 applies to anchors with a nominal diameter of 1/4 in. (6 mm) or larger.
The values stated either in inch-pound units or SI units are to be separately regarded. Within the text, the SI units are shown in parentheses. The values in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems shall result in nonconformance with ACI 355.2.
