* The tabulated values are for RX-38 anchors
installed at a minimum of 12-diameters on center and minimum edge of 6-diameters
for 100 percent anchor efficiency. Spacing and edge distance may be reduced
to 6 diameters and 3 diameter edge distance provided the values are reduced
50 percent. Linear interpolation may be used for intermediate spacing
and edge margins.
* Allowable values are based
upon a 4 to 1 safety factor. Divide by 4 for allowable load values.

Combined
Tension and Shear Loading—for Multi-Set Anchors
Allowable
loads for anchors subjected to combined shear and tension forces
are determined by the following equation:
(Ps/Pt) 5/3
+ (Vs/Vt) 5/3
< 1
Ps = Applied
tension load Vs = Applied shear load
Pt = Allowable tension load VT = Allowable shear
load
