Hello,
could someone give me a tipp how to divide in Sofistik the loadcases into short and long loadcases for check the stresses in concrete at SLS QP check. I have the problem with max concrete stresses and therefore I want to use different E modulus for short and for long loadcases.
Hello,
In Ase you could use the command GRP and change the stiffness of the concrete with a factor.
Grp No xxx Facs yyy.
Hard to say if this works for you without any further details
I think that we speak about two different issues - I don’t want to change the element stiffness when I determine the forces in cross sections but I want to change the stiffness because of creep when I design the reinforced cross section and for that I need the another curve for concrete in SLS for long loads and other (without creep factor) for short loadcases. How to change the concrete material curve in SLS I know - this option is available when I determine the concrete material. So “per hand”/manually I know how to do it but I want that Sofistik do it automatically (different SLS curves for short and for long loadcases) but maybe it is imposibble.
did you find the answer to your question? I am also interested in the answer
Unfortunatelly, I didn’t find the answer on my question. I read the whole manual and there was no answer on that (only something about long/short LC in timber structures). So, there is only one way - checking by every cross section manually 
Hi
You can use construction stages in aqua modify elastic modulus of material in specified stages.
f.e.
cs 5
sv face 0.25 mno 2
then in aqb you use BEAM CS1 5 to select your section in stage you want.
However above solution is not the best way to work, sofistik provides a lot better work flow for creep, check AQB manuals.
