4 Load-Adjustment Factors for Drop-In (Stainless Steel), Coil Thread (Carbon Steel) and Short Drop-In Anchors in Normal-Weight Concrete: and, and s How to use these charts:. The following tables are for reduced edge distance and spacing. 2. Locate the anchor size to be used for either a tension and/or shear load application. 3. Locate the edge distance ( ) or spacing (s act ) at which the anchor is to be installed. 4. The load adjustment factor (f c or f s ) is the intersection of the row and column. 5. Multiply the allowable load by the applicable load adjustment factor.. Reduction factors for multiple edges or spacing are multiplied together. (f c ) c cr c min f cmin See notes below. (f c ) c cr c min f cmin and (f s ) s act = actual edge distance at which anchor is installed (inches). 2. c cr = critical edge distance for 00% load (inches). 3. c min = minimum edge distance for reduced load (inches). 4. f c = adjustment factor for allowable load at actual edge 5. f ccr = adjustment factor for allowable load at critical edge f ccr is always =.00.. f cmin = adjustment factor for allowable load at minimum edge 7. f c = f cmin + [( f cmin ) ( c min ) / (c cr c min )] E S cr S min f smin E = Embedment depth (inches). 2. s act = actual spacing distance at which anchors are installed (inches). 3. s cr = critical spacing distance for 00% load (inches). 4. s min = minimum spacing distance for reduced load (inches). 5. f s = adjustment factor for allowable load at actual spacing. f scr = adjustment factor for allowable load at critical spacing f scr is always = f smin = adjustment factor for allowable load at minimum spacing 8. f s = f smin + [( f smin ) (s act s min ) / (s cr s min )]. 9.
