Information on this page has been updated since the printing of the 2007 Anchor Systems Catalog (C-SAS-2007).

How to use these charts:
- The following tables are for reduced Spacing.
- Locate the anchor size to be used for either a tension and/or shear load application.
- Locate the embedment (E) at which the anchor is to be installed.
- Locate the spacing (Sact) at which the anchor is to be installed.
- The load adjustment factor (fs) is the intersection of the row and column.
- Multiply the allowable load by the applicable load adjustment factor.
- Reduction factors for multiple spacings are multiplied together.
- Adjustment factors do not apply to allowable steel strength values.
- Adjustment factors are to be applied to allowable Tension Load Based on Bond Strength values only.
Spacing Tension (fs)
see notes below
Spacing Tension (fs) (cont'd)
- E = Embedment depth (inches).
- Sact = actual spacing distance at which anchors are installed (inches).
- Scr = critical spacing distance for 100% load (inches).
- Smin = minimum spacing distance for reduced load (inches).
- fs = adjustment factor for allowable load at actual spacing distance.
- fscr = adjustment factor for allowable load at critical spacing distance. fscr is always = 1.00.
- fsmin = adjustment factor for allowable load at minimum spacing distance.
- fs = fsmin + [(1 - fsmin) (Sact - Smin) / (Scr - Smin)].
