Simpson Anchor Systems: Drop-In (Carbon and Stainless Steel) and Lipped Drop-In (Carbon Steel) Anchors Load Adjustment Lightweight Concrete: Edge Distance, Tension Loads

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 edge distance (C_act) at which the anchor is to be installed.
The load adjustment factor (f_c) is the intersection of the row and column.
Multiply the allowable load by the applicable load adjustment factor.
Reduction factors for multiple edges are multiplied together.

C_act = actual edge distance at which anchor is installed (inches).
C_cr = critical edge distance for 100% load (inches).
C_min = minimum edge distance for reduced load (inches).
f_c = adjustment factor for allowable load at actual edge distance.
f_ccr= adjustment factor for allowable load at critical edge distance. f_ccr is always = 1.00.
f_cmin = adjustment factor for allowable load at minimum edge distance.
f_c = f_cmin + [(1 - f_cmin) (C_act - C_min) / (C_cr - C_min)].
