Combined Tension and Shear Loading—for Dynabolt Anchors
Allowable loads for anchors subjected to combined shear and tension forces are determined by the following equation:
(Ps/Pt) + (Vs/Vt) ≤ 1
Ps = Applied tension load Vs = Applied shear load Pt = Allowable tension load Vt = Allowable shear load

* To calculate the Allowable Load of the anchor, divide the Ultimate Load by 4. The tabulated values are for anchors installed in a minimum of 12 diameters on center and a minimum edge distance of 6 diameters for 100 percent
anchor efficiency. Spacing and edge distance may be reduced to 6 diameter spacing and 3 diameter edge distance, provided the values are reduced 50 percent. Linear interpolation may be used for intermediate
spacings and edge distances.
Note: N/A is defined as Not Advisable.
