a) anchor channel installed perpendicular to the edge
b) anchor channel installed parallel to the edge
Figure 4-4: Example for the calculation of anchor
channels with 6 anchors loaded in shear longitudinal to
the channel axis for concrete edge failure
4.1.2.6 Adjacent anchor channels:
Anchor channels may be arranged as shown in Figure
Figure 4-5. Adjacent anchor channels must be of same size
and consist of anchors with same type and embedment
depth. In case of anchor channel configurations according
to Figure 4-5b and Figure 4-5c loaded in shear in any
direction, the load shall be transferred to the adjacent
anchor channels by a single plate (see Figure 4-6).
a) anchor channel in linear arrangement
b) adjacent anchor channels arranged parallel to edge
(n

= 2)
c) adjacent anchor channels arranged perpendicular to
edge (n
1
= 2)

4.1.3 Requirements for design strength:
4.1.3.1 General:
The design strength of anchor channel systems under the
2015 IBC as well as Section R301.1.3 of the 2015 IRC must
be determined in accordance with ACI 318-14 Chapter 17
and this report.
The design strength of anchor channel systems under the
2012 IBC as well as Section R301.1.3 of the 2012 IRC must
be determined in accordance with ACI 318-11 Appendix D
and this report.
The design strength of anchor channel systems under the
2009 IBC as well as Section R301.1.3 of the 2009 IRC must
