* Edge and spacing distance shall be divided by .75 when anchors are
placed in structural lightweight concrete. Linear interpolation may
be used for intermediate spacing and edge distances.
For 5/8" and 3/4" LDT Anchors, the critical edge distance
for these anchors is 10 times the anchor diameter. The edge distance
of these anchors may be reduced to 1-3/4" provided a 0.65 load
factor is used for tension loads, a 0.15 load factor is used for shear
loads applied perpendicular to the edge, or a 0.60 load factor is
used for shear loads applied parallel to the edge. Linear interpolation
may be used for intermediate edge distances.
