Eccentric out of plane loading on group of bolts

I am working on a bracket (not an angle bracket) which has 4 anchor bolts attached to concrete wall and is under out of plane loading. I used ledger angle profile to simulate that (I am not worried about the strength of bracket). My question is how does hilti calculate the resultant anchor tension loads because of eccentric loads in attached file? I could not find any reference or calculations. As it is not a steel connection, we can not use the conventional out of plane loading loading on a bolt group so what calculations hilti uses?
