AT High Strength Acrylic-Tie® Anchoring Adhesive
Load Adjustment Factors in Normal-Weight Concrete:
Edge Distance, Tension Load
How to use these charts:
- The following tables are for reduced Edge Distance.
- Locate the anchor size to be used for either a tension and/or shear load application.
- Locate the embedment (E) at which the anchor is to be installed.
- Locate the edge distance (Cact) at which the anchor is to be installed.
- The load adjustment factor (fc) is the intersection of the row and column.
- Multiply the allowable load by the applicable load adjustment factor.
- Reduction factors for multiple edges are multiplied together.
- Adjustment factors do not apply to allowable steel strength values.
- Adjustment factors are to be applied to allowable Tension Load
Based on Bond Strength values only.
Edge Distance Tension (fc)
see notes below
Edge Distance Tension (fc) (cont'd)
- E = Embedment depth (inches).
- Cact = actual edge distance at which anchor is installed (inches).
- Ccr = critical edge distance for 100% load (inches).
- Cmin = minimum edge distance for reduced load (inches).
- fc = adjustment factor for allowable load at actual edge distance.
- fccr = adjustment factor for allowable load at critical edge distance. fccr is always = 1.00.
- fcmin = adjustment factor for allowable load at minimum edge distance.
- fc = fcmin + [(1 - fcmin) (Cact - Cmin) / (Ccr - Cmin)].
