DESIGN INFORMATION IN CONCRETE PER CSA A23.3
Limit State Design of anchors is described in the provisions of CSA A23.3-14 Annex D for post-installed anchors tested and
assessed in accordance with ACI 355.2 for mechanical anchors and ACI 355.4 for adhesive anchors. This section contains the
Limit State Design tables with unfactored characteristic loads that are based on the published loads in ICC Evaluation Services
ESR-1545. These tables are followed by factored resistance tables. The factored resistance tables have characteristic design
loads that are prefactored by the applicable reduction factors for a single anchor with no anchor-to-anchor spacing or edge
distance adjustments for the convenience of the user of this document. All the figures in the previous ACI 318-14 Chapter 17
design section are applicable to Limit State Design and the tables will reference these figures.
For a detailed explanation of the tables developed in accordance with CSA A23.3-14 Annex D, refer to Section 3.1.8. Technical
assistance is available by contacting Hilti Canada at (800) 363-4458 or at www.hilti.com.
