How to use these charts:

1. The following tables are for reduced spacing.
2. Locate the anchor size to be used for either a tension and/or shear load application.
3. Locate the spacing (S_act) at which the anchor is to be installed.
4. The load-adjustment factor ( f_s) is the intersection of the row and column.
5. Multiply the allowable load by the applicable load-adjustment factor.
6. Reduction factors for spacing are multiplied together.

Spacing Tension and Shear (f_s)

1. E = Embedment depth (inches).
2. S_act = actual spacing distance at which anchors are installed (inches).
3. S_cr = critical spacing distance for 100% load (inches).
4. S_min = minimum spacing distance for reduced load (inches).
5. f_s = adjustment factor for allowable load at actual spacing distance.
6. f_scr = adjustment factor for allowable load at critical spacing distance. f_scr is always = 1.00.
7. f_smin = adjustment factor for allowable load at minimum spacing distance.
8. f_s = f_smin + [(1 - f_smin) (S_act - S_min) / (S_cr - S_min)].
