How to use these charts:

  1. The following tables are for reduced edge distance.
  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 edge distance (Cact) at which the anchor is to be installed.
  5. The load-adjustment factor (fc) 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 are multiplied together.
  8. Adjustment factors do not apply to allowable steel strength values.
  9. Adjustment factors are to be applied to allowable Tension Load Based on Bond Strength values or allowable Shear Load Based on Concrete Edge Distance values only.
Tension Load Normal Weight Concrete Edge Distance
Edge Distance Tension (fc)
  1. E = Embedment depth (inches).
  2. Cact = actual edge distance at which anchor is installed (inches).
  3. Ccr = critical edge distance for 100% load (inches).
  4. Cmin = minimum edge distance for reduced load (inches).
  5. fc = adjustment factor for allowable load at actual edge distance.
  6. fccr = adjustment factor for allowable load at critical edge distance. fccr is always = 1.00.
  7. fcmin = adjustment factor for allowable load at minimum edge distance.
  8. fc = fcmin + [(1 - fcmin) (Cact - Cmin) / (Ccr - Cmin)].
Shear Load Normal Weight Concrete Edge Distance
Edge Distance Shear (fc)
  1. E = Embedment depth (inches).
  2. Cact = actual edge distance at which anchor is installed (inches).
  3. Ccr = critical edge distance for 100% load (inches).
  4. Cmin = minimum edge distance for reduced load (inches).
  5. fc = adjustment factor for allowable load at actual edge distance.
  6. fccr = adjustment factor for allowable load at critical edge distance. fccr is always = 1.00.
  7. fcmin = adjustment factor for allowable load at minimum edge distance.
  8. fc = fcmin + [(1 - fcmin) (Cact - Cmin) / (Ccr - Cmin)].
