How to use these charts:
- The following tables are for reduced Spacing.
- Locate the anchor size to be used for a shear load application. (See Tension Loads for tension load applications)
- Locate the anchor embedment (E) used for a shear load application. (See Tension Loads for tension load applications)
- Locate the edge 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(s).
- Reduction factors for multiple spacings are multiplied together.
Spacing Shear (fs)
See Notes Below
- 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)].
