INTRODUCTION
The design of an anchor channel system depends on two different aspects; substrate type and
applied loads. They are both equally important and therefore they are both essential for an accurate
anchor channel analysis. The design introduction opens up the sections that cover the design of an
anchor channel.

INTRODUCTION
4.1 PUBLISHED LOAD VALUES 4.3 ANCHOR CHANNEL DESIGN
Technical data presented herein was current as of the date of
publication (see back cover). Anchor channel strength (capacity)
published in this technical manual are based on International
Council Code Evaluation Research Report 3520 (ICC ESR-3520)
when applicable. Likewise, analytical calculations are based on
ICC ESR-3520 and ACI 318 when applicable. Acceptance Criteria for Anchor Channels in Concrete Elements
(AC232) establishes the requirements for anchor channels in
normal weight or lightweight concrete elements comply with
International Building Code Evaluation Service, LLC (ICC-ES),
evaluation report under the 2018, 2015, 2012, 2009, and 2006
International Building Code (IBC) and the 2018, 2015, 2012,
2009, and 2006 International Residential Code (IRC). The
bases of compliance are IBC Section 104.11, and IRC Section
R104.11. AC232 requires the verification of up to 20 different
anchor channel failure modes, in addition to 6 additional anchor
reinforcement failure modes if anchor reinforcement is used.
Moreover, a total of up to 5 different interaction equations are
required.
Capacity (strength) of anchor channels outside the scope of
ICC ESR-3520 are based on applicable testing protocols of
Acceptance Criteria 232 (AC232). Load values obtained from
testing represent the average results of multiple identical
samples. Analytical calculations are based on applicable design
provisions of AC232 and ACI 318.
Variations in base materials such as concrete and local
site conditions require on-site testing to determine actual
performance at any specific site.
The tables and diagrams in this guide are intended purely as an
aid to the user and no guarantee can be given regarding their
correctness or accuracy when used for design calculations
for a specific application. Should you, despite the care we
have taken, discover an error in the information given here,
please notify us accordingly. In any event, the static system or,
respectively, the specific application must always be checked
for plausibility by the user.

The design process of an anchor channel requires the
verification of its structural adequacy to resist specific loads.
Nowadays, design software such as PROFIS Anchor Channel
facilitates and helps to speed up the design process. However,
in order to utilize the software at its maximum potential and
ensure the design is correct, a thorough understanding of
several requirements is needed. For instance, PROFIS Anchor
Channel does not allow the input of a cold join in the substrate
element. On the other hand, even when a specific condition is
fully covered by the software, one must still understand these
elements for a proper design.
Such elements are as follows:
Base material (chapter 5)
Applied loads (chapter 6)
Anchor strength (chapter 2)
Anchoring to concrete theory and design guidelines (chapter 7)
Reinforcing bar theory (chapter 8)
4.2 UNITS
Technical data is provided in Imperial units. Metric values,
when provided, use the International System of units (SI)
in observance with the Metric Conversion Act of 1975 as
amended by the Omnibus Trade and Competitiveness Act of
1988. MI and MQ connector and base dimensions are converted
from SI units, shown in parentheses, to Imperial units.
