How to use these charts:

  1. The following tables are for reduced End and Edge Distance and Spacing.
  2. Locate the anchor size to be used for either a tension and/or
    shear load application.
  3. Locate the embedment (E) at which the anchor is to be installed.
  4. Locate the end or edge distance (Cact) or spacing (Sact) at which the
    anchor is to be installed.
  5. The load adjustment factor (fc or fs) is the intersection of the row and column.
  6. Multiply the allowable load by the applicable load adjustment factor.
  7. Reduction factors for multiple edges or spacing are multiplied together.
Tension Load Concrete Block (CMU)
Edge or End Distance Tension (fc)

Edge Distance Tension
Tension Load Concrete Block (CMU)
Edge and End Distance Shear (fc) Shear Load Parallel to Edge or End

End Distance Shear - Shear Load Parallel to Edge or End

  1. E = Embedment depth (inches).
  2. Cact = actual end or edge distance at which anchor is installed (inches).
  3. Ccr = critical end or edge distance for 100% load (inches).
  4. Cmin = minimum end or edge distance for reduced load (inches).
  5. fc = adjustment factor for allowable load at actual end or edge distance.
  6. fccr = adjustment factor for allowable load at critical end or edge distance. fccr is always = 1.00.
  7. fcmin = adjustment factor for allowable load at minimum end or edge distance.
  8. fc = fcmin + [(1 - fcmin) (Cact - Cmin) / (Ccr - Cmin)].

End and Edge Distance Shear

  1. E = Embedment depth (inches).
  2. Cact = actual end or edge distance at which anchor is installed (inches).
  3. Ccr = critical end or edge distance for 100% load (inches).
  4. Cmin = minimum end or edge distance for reduced load (inches).
  5. fc = adjustment factor for allowable load at actual end or edge distance.
  6. fccr = adjustment factor for allowable load at critical end or edge distance. fccr is always = 1.00.
  7. fcmin = adjustment factor for allowable load at minimum end or edge distance.
  8. fc = fcmin + [(1 - fcmin) (Cact - Cmin) / (Ccr - Cmin)].

Spacing Shear

  1. E = Embedment depth (inches).
  2. Sact = actual spacing distance at which anchors are installed (inches).
  3. Scr = critical spacing distance for 100% load (inches).
  4. Smin = minimum spacing distance for reduced load (inches).
  5. fs = adjustment factor for allowable load at actual spacing distance.
  6. fscr = adjustment factor for allowable load at critical spacing distance. fscr is always = 1.00.
  7. fsmin = adjustment factor for allowable load at minimum spacing distance.
  8. fs = fsmin + [(1 - fsmin) (Sact - Smin) / (Scr - Smin)].
