DESIGN INFORMATION IN CONCRETE PER CSA A23.3
Limit State Design of anchors is described in the provisions of CSA A23.3 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-4386 . 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 anchorto-anchor spacing or edge distance adjustments for the convenience of the user of this document . All the figures in the previous ACI 318 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 Annex D , refer to PTG Ed . 21 Section 3.1.8 . Technical assistance is available by contacting Hilti Canada at ( 800 ) 363-4458 or at www . hilti . com .
