Cast-in anchor channels with rebar anchors for face of slab
applications
The overall design of HAC CRFoS U follows the principles
described in chapter 7 with some modifications to the
verification of some failure modes. Table 9.3.1.1, 9.3.1.2, 9.3.1.3,
Figures 9.3.1.1 and 9.3.1.2 illustrate the main differences in the
possible failures modes of HAC and HAC CRFoS U.

The tests follow AC232 testing

theory for further clarification. Please
refer table 2.3.4.3 for strength values.

Example
Concrete breakout in tension and pry-out failure modes were
not observed in testing, and therefore, they are excluded from
the possible failure modes of HAC CRFoS U. The verification
of the adequacy of the pull-out strength of the rebar anchors is
based on ACI 318. The design ensures the applied rebar forces
do not exceed the bond stresses between the rebar and the
concrete.

Please refer to anchor channel theory
for more information on this failure

same as that of headed stud anchor
channel. This check is compliant with
ESR 3520.
