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 ESR-4386 and the equations within ACI 318 Chapter 17 . For a detailed explanation of the Hilti Simplified Design Tables , refer to section 3.1.8 of the North American Product Technical Guide , Volume 2 : Anchor Fastening Technical Guide , Edition 22 ( PTG Ed . 21 ). Data tables from ESR-4386 are not contained in this section but can be found at www . icc-es . org or at www . hilti . com .

1 See PTG Ed . 21 section 3.1.8 to convert design strength value to ASD value . 2 Linear interpolation between concrete compressive strengths is not permitted . 3 Apply spacing , edge distance , and concrete thickness factors in tables 5 to 8 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 Tabular values are for static loads only . Seismic design is not permitted for uncracked concrete . For all seismic tension loads for all other anchors , multiply cracked concrete tabular values in tension only by the following reduction factors : M24 - α N , seis = 0 . 62 . HSL4-G M24 is not approved for seismic design . All other sizes - α N , seis = 0.75 No reduction needed for seismic shear . See PTG Ed . 21 section 3.1.8 for additional information on seismic applications .
