Why is Profis using an hef value of 69.7mm when the embedment is only 60mm

Thanks for your question. I see from looking from your extract you have modelled the HUS4-H12 x 100 40/20 with h-nom1.
Your baseplate thickness has been modelled as 12mm however I can not see your load input so I’m assuming this is a nominal load.

What you have is an anchor that can be installed at varying embedment depths depending upon the load resistance requirements and the required fastenable thickness.

So to confirm the drill hole length h1 is the necessary length of the hole to be drilled, the nominal embedment depth hnom (In this case hnom equates to 100 – 12 = 88mm as shown in the extract) is the length between the end of the anchoring element and the concrete surface and the calculated effective embedment depth h_ef 69.7 [mm] is the embedment depth to be taken into account when calculating the concrete cone failure load of bonded anchors and metal anchors, pullout failure load for bonded anchors etc.

The (h_ef,ETA = 45.9) is the minimum value that the software can use based upon the ETA. Now then, if you revisit your example but just increase your fasteneable thickness to 40mm your would then see the h,nom is 60mm , h_ef = 45.9mm and the h_ef,ETA =45.9mm and that it is not possible to further increase the fastenable thickness for this anchor.

So you can be reassured that the software is performing as it should.
