To optimize the design,use Hilti PROFIS Engineering software or perform anchor calculation using design equations from ACI 318-14 Chapter 17. 3 Spacing factor reduction in shear,fAN,assumes an influence of a nearby edge.If no edge exists,then f Av=fAN. 4 Concrete thickness reduction factor in shear,f Hv,assumes an influence of a nearby edge.If no edge exists,then f Hv=1.0. 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 table 5 and figure 2 of this section to calculate permissable edge distance,spacing and concrete thickness combinations. KWIK HUS-EZ SCREW ANCHOR-July 2020 5
