DESIGN INFORMATION IN CONCRETE PER ACI 318
ACI 318 Chapter 17 Design
The load values contained in this section are Hilti Simplified Design Tables . The load tables in this section were developed using the Strength Design parameters and variables of ICC-ES ESR-4266 and the equations within ACI 318 Chapter 17 . For a detailed explanation of the Hilti Simplified Design Tables refer to section 3.1.8 . Data tables from ESR-4266 are not contained in this section but can be found at www . icc-es . org or at www . hilti . com

1 See Section 3.1.8 to convert design strength value to ASD value . 2 Linear interpolation between embedment depths and concrete compressive strengths is not permitted . 3 Apply spacing , edge distance , and concrete thickness factors in tables 6 to 15 as necessary . Compare to the steel values in table 4 . The lesser of the values is to be used for the design . 4 Tabular values are for normal weight concrete only . For lightweight concrete multiply design strength by λ a as follows : For sand-lightweight , λ a = 0.68 ; for all-lightweight , λ a
= 0.60 .
5 For core drilled installations of 3 / 4 ” anchors installed at 3-3 / 4 ” effective embedment , apply a reduction factor of 0.89 to the design tension strength .
