Bar Anchorage
If forces act in more than one direction the combination of loads has to be verified. Anchor channels subjected to combined axial
and shear loads shall be designed to satisfy the following requirements by distinguishing between steel failure of the channel bolt,
steel failure modes of the channel and concrete failure modes.

Concrete breakout strength for parallel shear: The concrete
breakout strength for parallel shear is calculated according ESR
for both channels are verified independently and neglecting
the EDGE front plate. The concrete utilization of both edges is
then combined in conservative way as described in the next
paragraph.
