TITEN HD® Heavy Duty Screw Anchor for Concrete & Masonry
Load-Adjustment Factors
in Normal-Weight Concrete: Edge Distance, Tension and Shear Loads
These tables are not for use with USD design methods
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 anchor embedment (E) used for either a tension and/or shear
load application.
- 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(s).
- Reduction factors for multiple edges are multiplied together.
Edge Distance Tension (fc)
The tabled adjustment values (fc) have been calculated using the following information:
- 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 = percent of allowable load at actual edge distance.
- fccr = percentage of allowable load at critical edge distance. fccr is always = 1.00.
- fcmin = percent of allowable load at minimum edge distance.
- fc = fcmin + [(1 - fcmin) (Cact - Cmin) / (Ccr - Cmin)].
Edge Distance Shear (fc)
The tabled adjustment values (fc) have been calculated using the following information:
- 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 = percent of allowable load at actual edge distance.
- fccr = percentage of allowable load at critical edge distance. fccr is always = 1.00.
- fcmin = percent of allowable load at minimum edge distance.
- fc = fcmin + [(1 - fcmin) (Cact - Cmin) / (Ccr - Cmin)].
