1 Linear interpolation not permitted . 2 Spacing factor reduction in shear , f AV
, assumes an influence of a nearby edge . If no edge exists , then f AV = f AN
.
3 Concrete thickness reduction factor in shear , f HV , assumes an influence of a nearby edge . If no edge exists , then f HV
= 1.0 . 4 When combining multiple load adjustment factors ( e . g . for a 4 anchor pattern in a corner with thin concrete member ) the design can become very conservative .
To optimize the design , use Hilti PROFIS Engineering software or perform anchor calculation using design equations from ACI 318 Chapter 17 or CSA A23.3 Annex D .
— If a reduction factor value is in a shaded cell , this indicates that this specific edge distance may not be permitted with a certain spacing ( or vice versa ). Check with Figure 2 of this section to calculate permissable edge distance and spacing combinations .
