1 Linear interpolation not permitted 2 When combining multiple load adjustment factors ( e . g . for a four-anchor pattern in a corner with thin concrete member ) the design can become very conservative . To optimize the design , use

PROFIS Engineering or perform anchor calculation using design equations from ACI 318 Chapter 17 . 3 Spacing factor reduction in shear applicable when c < 3 * h _ef

. ƒ _AV , is applicable when edge distance , c < 3 * h _ef

. If c ≥ 3 * h _ef , then ƒ _AV

= ƒ _AN .

4 Concrete thickness reduction factor in shear , ƒ _HV , is applicable when edge distance , c < 3 * h _ef

. If c ≥ 3 * h _ef , then ƒ _HV

= 1.0 . ƒ _HV
