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 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. HSL-3-G is not approved for seismic
design. 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
All other sizes - α
N,seis
= 0.75
No reduction needed for seismic shear. See section 3.1.8 for additional information on seismic applications.
DESIGN DATA IN CONCRETE PER ACI 318
ACI 318-14 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-1545 and the equations within ACI 318-14 Chapter 17. For a
detailed explanation of the Hilti Simplified Design Tables, refer to section 3.1.8. 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.
