TITEN HD ®<br />
Load-Adjustment Factors for Titen HD ® <strong>Anchors</strong> in Normal-Weight Concrete:<br />
Spacing, Tension <strong>and</strong> Shear Loads<br />
How to use these charts:<br />
1. The following tables are for reduced spacing.<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 />
Spacing Tension (fs)<br />
Sact<br />
(in.)<br />
4. Locate the spacing (S act ) at which the anchor is to be installed.<br />
5. The load adjustment factor (f s ) 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 spacings 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 (fs)<br />
have been calculated using the<br />
following information:<br />
1. E = Embedment depth (inches).<br />
2. Sact = actual spacing distance at<br />
which anchors are installed<br />
(inches).<br />
3. Scr = critical spacing distance for<br />
100% load (inches).<br />
4. Smin = minimum spacing distance<br />
for reduced load (inches).<br />
5. fs = adjustment factor for<br />
allowable load at actual<br />
spacing distance.<br />
6. fscr = adjustment factor for<br />
allowable load at critical spacing<br />
distance. fscr is always = 1.00.<br />
7. fsmin = adjustment factor for<br />
allowable load at minimum<br />
spacing distance.<br />
8. fs = fsmin + [(1 - fsmin)<br />
(Sact - Smin) / (Scr - Smin)].<br />
