i don't know if is a Sap bug or a fault of me, but for the Z direction in my post i have the same result if i scale the time history by gravity acceleration or i do not (and is a 981 factor).
Can we work...
The answer seems simple, so sorry if i have not truly understanded what you need.
If you work in linear, i'd run as many analysis cases as i need, then i'd define Combos entering the cases and the safety factors you need, linear adding a case to another.
