SLEEVE-ALL ®<br />
Load-Adjustment Factors for Sleeve-All ® <strong>Anchors</strong> in Normal-Weight Concrete:<br />
Edge Distance <strong>and</strong> Spacing, Tension <strong>and</strong> Shear Loads<br />
How to use these charts:<br />
1. The following tables are for reduced edge distance <strong>and</strong> spacing.<br />
2. Locate the anchor size to be used for either a tension <strong>and</strong>/or<br />
shear load application.<br />
3. Locate the edge distance (Cact ) or spacing (Sact ) at which<br />
the anchor is to be installed.<br />

4. The load adjustment factor (f c or f s ) is the intersection of the row<br />
<strong>and</strong> column.<br />
5. Multiply the allowable load by the applicable load adjustment factor.<br />
6. Reduction factors for multiple edges or spacing are multiplied together.<br />

of the load table<br />

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