DESIGN DATA IN CONCRETE PER ACI 318
ACI 318 Chapter 17 Design The technical data contained in this section are Hilti Simplified Design Tables . The load values were developed using the Strength Design parameters and variables of ESR-4145 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-4145 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 concrete compressive strengths is not permitted .
3 Tabular values are for single anchor located at edge distance ( c ) and spacing ( s ) greater than 24 ". For anchors with edge distance or spacing less than 24 " use ACI 318 to calculate load reduction factor . Compare the value to the steel values ( threaded rod and inserts ) in Tables 4 and 5 . 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
= 0.85 .
For all-lightweight , λ a
= 0.75 5 Tabular values are for static loads only . Seismic design is not permitted for uncracked concrete .
