1 Linear interpolation not permitted 2 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 Design software or perform anchor calculation using design equations from ACI 318 Ch . 17 or CSA A23.3 Annex D . 3 Spacing factor reduction in shear , f AV
, is applicable when edge distance c < 3h ef . If c ≥ 3h ef then f AV = f AN
.
4 Concrete thickness reduction factor in shear , f HV , is applicable when edge distance c < 3h ef
. If c ≥ 3h ef then f HV
= 1.0 .
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 3 and Table 21 to calculate permissible edge distance , spacing and concrete thickness combinations .
