Concrete breakout strength for perpendicular
shear
The pryout failure is calculated based on the N cb as indicated
above both for longitudinal and perpendicular shear. Test
restults show that two anchor channels that are located at the
corner k cp for pry out check can be used as 3. k cp =3 is used for
two corner anchors located at the corner edge. A similar consideration on the modification factor for the
anchor spacing can be done for the concrete edge failure for
perpendicular shear. Figure 9.2.10.11 shows a similar approach
to that proposed for the concrete cone for the concrete edge
breakout for perpendicular shear. If two channels are located
at a distance d a1,b1 smaller than C cr,V (Figure 9.2.10.11 b) the
concrete edge failure of the two channels would intersect and
the capacity of the system will be reduced. In this case, all the
anchors of both channels are considered for the calculation of
the modification factor Ψ s,V .

s i is calculated with d*= c a2,a + (c a2,b − c 1 ) fictitious distance
between channel a and b.
If c a1,a ≠ c a1,b both channel will be considered as with
c 1 = min(c a1,a ; c a1,b )
Therefore, it is proposed to calculate the factor Ψ s,V with the two
anchor channels placed in a row with the edge of “fictitious”
edge distance d ∗ :
Where c, is the minimum edge distance of channel a and
channel b. In case that c a1,a and c a1,b are different, the minimum
will be assumed for the calculation of both channels.

Figure 9.2.10.11b — anchor channels adjacent to each other.
Placing two channels close to a corner (Figure 9.2.10.11 c),
it is possible to calculate the channels with the method of
“unfolding” the edge (Figure 9.2.10.11 d). Doing this operation, a
fictitious distance between the two channels has to be defined
and it is important to make sure that the corner area is used
only once. In the case of Figure 9.2.10.11 c the area which can
be considered only once is represented with black rectangle. If
the channel a collapses under shear load, then the area in black
would also collapse. The channel b would be left only with the
area up to the black rectangle to resist shear loads. The same
consideration is made for the channel b.
