Load-Adjustment Factors for Titen HD ® <strong>Anchors</strong> in Normal-Weight Concrete:<br />
Edge Distance, Tension <strong>and</strong> Shear Loads<br />
How to use these charts:<br />
1. The following tables are for reduced edge distance.<br />
2. Locate the anchor size to be used for either a tension<br />
<strong>and</strong>/or shear load application.<br />
3. Locate the anchor embedment (E) used for either a tension<br />
<strong>and</strong>/or shear load application.<br />
Edge Distance Tension (fc)<br />

(in.)<br />
4. Locate the edge distance (C act ) at which the anchor is to be installed.<br />
5. The load adjustment factor (f c ) is the intersection of the row <strong>and</strong> column.<br />
6. Multiply the allowable load by the applicable load adjustment factor(s).<br />
7. Reduction factors for multiple edges are multiplied together.<br />

explanation of the<br />
load table icons<br />
These tables are not for use<br />
with USD design methods<br />
The tabled adjustment values (fc)<br />
have been calculated using the<br />
following information:<br />
1. E = Embedment depth (inches).<br />
2. Cact = actual edge distance at<br />
which anchor is installed (inches).<br />
3. Ccr = critical edge distance for<br />
100% load (inches).<br />
4. Cmin = minimum edge distance<br />
for reduced load (inches).<br />
5. fc = percent of allowable load at<br />
actual edge distance.<br />
6. fccr = percentage of allowable load<br />
at critical edge distance. fccr is<br />
always = 1.00.<br />
7. fcmin = percent of allowable load<br />
at minimum edge distance.<br />
8. fc = fcmin + [(1 - fcmin)<br />
(Cact - Cmin) / (Ccr - Cmin)].<br />
