Corner distance facts:
• Any edge which the distance parallel to the long axis of the
anchor channels is considered a corner
• For determination of the minimum corner distance,
c a2 = min of c a2,1 and c a2,2
• Corner distances are always measured from the center of the
anchor under consideration
* M
inimum slab thickness, h min may be reduced if anchor cover requirements can be omitted
(i.e. interior applications with metal deck underneath the channel). To avoid splitting of the
concrete, the minimum edge and corner distance shall be increased by a factor of 2.

• Any edge which the distance perpendicular to the long axis of
the anchor channels is considered an edge.
• For determination of the minimum edge distance of
• concrete breakout strength in tension,
c a1 = min of c a1,1 and c a1,2
• For analysis purposes of concrete edge breakout strength in
shear, c a1 is always measured in the direction of the applied
shear load.
• Edge distances are always measured from the center of the
anchor under consideration.

Channel Design
The minimum edge distance and member thickness for anchor
channels are established via testing. It is the interaction
between minimum member thickness and minimum edge
distance that determines the minimum edge distance. If the
anchor channel is installed closer than the minimum edge
distance, cracking of the concrete may occur while applying
the required installation torque to the t-bolts. Testing to
determine the minimum edge distance considers unfavorable
site conditions. The test is based on having the anchor channel
recessed 1/8" in unreinforced concrete. Splitting/cracking
may occur. Therefore, minimum substrate requirements
vary depending on the anchor channel size. HAC substrate
requirements are provided in Table 2.2.1.2 and 2.2.1.3.
