Wedge-All® Wedge Anchors

Load-Adjustment Factors

for Carbon-Steel and Stainless-Steel Wedge-All® Anchors

in Normal-Weight Concrete: Spacing, Tension Loads

 

How to use these charts:

  1. The following tables are for reduced spacing.
  2. Locate the anchor size to be used for a tension load application.
  3. Locate the anchor embedment (E) used for a tension load application.
  4. Locate the edge spacing (Sact) at which the anchor is to be installed.
  5. The load-adjustment factor (fs) is the intersection of the row and column.
  6. Multiply the allowable load by the applicable load-adjustment factor(s).
  7. Reduction factors for multiple spacings are multiplied together.

  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)].
