AT High Strength Acrylic-Tie® Anchoring Adhesive

Load Adjustment Factors in Normal-Weight Concrete:

Spacing, Shear Load

How to use these charts:

  1. The following tables are for reduced 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 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.
  7. Reduction factors for multiple spacings are multiplied together.
  8. Adjustment factors do not apply to allowable steel strength values.
  9. Adjustment factors are to be applied to allowable Shear Load Based on Concrete Edge Distance values only.
 
Shear Load Normal Weight Concrete Spacing
Spacing Shear (fs)
at load adjustments - 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)].
