Applications
Anchors covered by ACI 318
ACI 318
(Chapter 19) (Appendix D or Chapter 17)
Model code compliance via ACI 318
AC232 removes the boundaries of manufacturers technical
data and limitations of testing data. Additionally, it takes into
consideration additional design parameters that have not been
neglected in the past such as cracked concrete, supplementary
reinforcement, anchor reinforcement, 95 percent fractile,
member thickness, etc.
Anchor channel design in accordance to an ICC-ES
Acceptance Criteria will help show compliance with the
model code. It protects public health, safety, and general
welfare. When the design is model code compliant
reduces the risk of delays or job site shut downs due to
noncompliant designs.

11.2 HILTI ANCHOR CHANNEL PRICE INDEX
11.2.1 HAC PRICE INDEX OF STANDARD PORTFOLIO
The objective of the chart below is to guide designers the ability to select not only the most feasible anchor channel solution,
but the anchor channel that makes the most sense for each specific project. The higher the channel is on the scale, the more
expensive the channel is. The scale ranges from 0 to 1. Although this chart does not provide the actual cost of the product, the
price difference ratio is consistent. Information may vary and therefore, is for preliminary selection purposes. Please consult your
local account manager for pricing information.
Anchors excluded from ACI 318
i.e. specialty inserts
Acceptance Criteria
AC232 provisions act as
amendments to ACI 318
Anchoring to Concrete
provisions. *The scope of
AC232 is limited to anchor
channel systems.
ESR
IBC
6. Loading
Specialty inserts are excluded from the Anchoring to Concrete
provisions of ACI 318. Acceptance Criteria 232 (AC232) was
develop to show anchor channels systems for recognition
under the IBC. AC232 provides testing and design guidelines
for cast-in anchor channel systems. Although, specialty inserts
are not within the current scope of ACI 318, AC232 Section 3.0
Design Requirements provides recommended additions to the
ACI 318 anchor to concrete provisions that permit the design of
anchor channel systems as if they were included in AC 318.

11.1.2 ANCHOR CHANNELS OUTSIDE THE SCOPE OF AC232
AC232 is a relatively new acceptance criteria. Seismic
provisions were only added in 2015. The long term goal is to
provide a work frame that covers all applications encountered
in a project and anchor channels needed to meet the required
design parameters,
Only anchor channels with rounded headed anchors or I
anchors and straight deformed bars are covered by AC232.
Therefore, only HAC can be shown compliant with an ESR.
However, there are still applications that require the use of
anchor channels not fully covered by AC232, such is the case of
HAC CRFoS U and HAC EDGE.
For applications outside the scope of AC232, Hilti has
developed design models based on applicable testing protocols
and design provisions of AC232. For failure modes outside the
scope of AC232 (i.e. pullout strength of a rebar), the principles of
AC232 and ACI 318 are followed.

Cast-in anchor channels systems are slotted connections
consisting of a steel channel, anchor element, and matching
t-bolts. Therefore, anchor channel systems are considered
specialty inserts.
