is no less than 1/2".
4) An edge distance of 1.5 x I
E
implies that the minimum distance from the corner of the wall to the centerline of the strap is no less than 1.5 times the embedment depth.
5) For edge distances between 1/2" and 1.5 x l
E
calculate loads using straight line interpolation.
6) Minimum anchor spacing for full capacity is 2 x l
E
. For spacing less than that reduce capacity proportionally.
