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

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

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