Anchor Fastening Technical Guide, Edition 21
<br /> DESIGN DATA IN CONCRETE PER ACI 318
<br /> ACI 318 Chapter 17 Design
<br /> The design tables in Tables 2 to 4 are Hilti Simplified Design Tables. The load values were developed using the design
<br /> parameters and variables of ICC Evaluation Services ESR-4236 and the equations within ACI 318 Chapter 17 as amended by
<br /> ICC-ES AC193. The strength design capacities calculated from the tables below are to be compared to the factored loads
<br /> determined from strength design load combinations. For a detailed explanation of the Hilti Simplified Design Tables, refer to
<br /> Section 3.1.8. Data tables from ESR-4236 are not contained in this section, but can be found at www.hilti.com or
<br /> www.icc-es.org.

<br /> The following footnotes apply to both Table 2 and 3:
<br /> 1 See Section 3.1.8.6 of the Anchor Tech Guide Ed.17 to convert design strength value to ASD value.
<br /> 2 Linear interpolation between concrete compressive strengths is not permitted.
<br /> 3 Tabular values are for a single anchor with a minimum edge distance of 6-1/2-in(166mm)and a minimum spacing of 8-in(204mm). For a 6-in(153mm)edge distance multiply
<br /> uncracked concrete tension and shear values by 0.92. No reduction needed for cracked concrete.
<br /> 4 Compare to the steel values in Table 4. The lesser of the values is to be used for the design.
<br /> 5 Tabular values are for normal weight concrete only. For lightweight concrete multiply design strength by A,as follows:For sand-lightweight,A,=0.68. For all-lightweight,A,=0.60.
<br /> 6 Tabular values are for static loads only. For seismic tension loads,multiply cracked concrete tabular values in tension by aN,,,,=0.74.
<br /> 7 No additional reduction needed for seismic shear for concrete breakout or pryout failure. See Section 3.1.8.7 of the Anchor Tech Guide Ed.17 for additional information on seismic
<br /> applications.
