Applications
The general design of HAC and HAC-T is based on ICC ESR-
3520. The design theory of rounded headed anchors is
presented in chapter 7. This section provides additional design
information for applications outside the scope of AC232 and
therefore ESR-3520 such as corners and parallel channels.

not depend on the concrete and therefore, the steel strengths of
HAC and HAC-T are based on ESR-3520.
This section provides guidelines to determine the concrete
strengths of anchor channels for applications outside the scope
of AC232. The design methodology of such applications is
based on applicable provisions and principles of AC232. Table
9.2.1 summarizes the design methodology for each potential
failure mode of HAC and HAC-T for intermediate, corners, and
parallel anchor channels applications.
The anchor channel design encompasses the verification of
the steel and concrete at the anchorage zone. For conditions
outside the scope of AC232, it is only the concrete failure mode
that are excluded. The steel strengths of the anchor channel do

AC232 based indicates product has been tested in accordance to AC232 testing protocols for that specific failure mode and the design is based on applicable provisions and/or
fundamentals of AC232 and/or ACI 318.
2 AC232 and ACI 318 based indicates the analysis of that specific failure modes is in accordance to the applicable ACI 318 provision.
IMPORTANT! Failure analysis modes evaluated follow ACI 318-14,
chapter 17. This DOES NOT include evaluating the base material (e.g.
edge-of-slab) capacity to resist compressive forces generated by
the fixture. The engineer must ALWAYS verify the base material (e.g.
edge-of-slab) design is capable of resisting the applied loading.
