DESIGN DATA IN CONCRETE PER ACI 318
ACI 318 Chapter 17 design
The load values 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 1545 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 Hilti Product Technical Guide Volume 2-21 . Data tables from ESR 1545 are not contained in this section , but can be found at www . icc-es . org or at www . hilti . com .

1 See Section 3.1.6 for explanation on development of load values . 2 See Section 3.1.9 to convert design strength value to ASD value . 3 Linear interpolation between concrete compressive strengths is not permitted . 4 Apply spacing , edge distance , and concrete thickness factors in tables 6 to 9 as necessary . Compare to the steel values in table 4 . The lesser of the values is to be used for the design . 5 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 .
6 Tabular values are for static loads only . Seismic design is not permitted for uncracked concrete . For seismic tension loads , multiply cracked concrete tabular values in tension only by
α N , seis
= 0.75 . See Section 3.1.9 of Hilti Product Technical Guide Volume 2-19 for additional information on seismic applications .
