ACI 318 14 splitting is assumed to be precluded by satisfying minimum edge distance and anchor spacing requirements Governing equations for each failure mode provided in ACI 318 14 demonstrate that the design strength of a CI anchor is affected by many parameters such as material properties of the steel and concrete bolt diameter embedment depth head or nut
The minimum distance between the top of the pole and the position of the Guy Hook must be 3 in length

2007 09 27 nbsp 0183 32 There really is no minimum edge distance required unless the anchor rods are in tension As long as you have some meat between the hole and edge of plate you re OK See also the link below
It will help you determine ahead of time the proper length of guy wires and the distance from the base of the mast to the anchor points All of the information contained within the article is based on Rohn engineering specifications for their H series telescoping masts All masts represented in this article are in 10 foot telescoping sections and Rohn recommends guying every 10 feet
2018 04 06 nbsp 0183 32 As you can see in the left example with a steep angle there is significantly more force on the guy wire and the mast for the same wind load As a rule of thumb anchor points about as far away from the base as the pole is high is a good compromise between strength and minimizing wire length and footprint

Double this distance to determine the minimum distance required between the base and the anchor For example if the guy line is attached 10′ up the pole the anchor should be a minimum of 20′ from the base see figure 88 If your line is long enough it won t hurt to place the anchor a few feet further out 3 2 1 ANCHOR As the name implies the 3 2 1 anchor is
