Hello everyone
To see SSI effects in design, I need to model a half-space soil medium under a mat footing slab instead of common simplified Winkler springs. I need to do it in ETABS by gap LINK elements as noted here:

Any help...
Beside going to Moon and Mars or making atomic bomb I don't know what the mankind has done with this. Since we can see it in all foundations like in elevator well and mechanical rooms or etc.

If there would be such a great financial or architectural feasibility the most easiest way was to design both slabs in one then fill the higher part to reach the needed level, even in this case you had less torsion in upper structure and everything was OK.

RISA couldn't help too.
Thanks my friends. Me myself model it separately then add retaining wall, but this way doesn't see the interaction of two slabs. Here almost all structural engineers do this and accept the approximation. Some others design two level in one but I think its not true.
I didn't hear the method...
I use CSI SAFE 14 to design foundations usually. SAFE claims it can design foundations in different elevations, but it can't. So I need to know which software is able to design multi-level strip foundations?
In attachment I've provide a simple example to know what I'm talking about.
Any help...
Thank you. But that is the way I've done for 5 years.
As I said I want to know if there is an option or a tricky way to assign specific combinations to each object BEFORE analyze then design ALL structure just by ONE action (one click on start check/design structure icon) to prevent manually...
Suppose that we have 3 load combinations named Comb1, Comb2 and Comb3. After running analysis we want to design beams by Comb1, braces by Comb2 and columns by Comb3 and for example braces should not design by Comb1 or Comb3.
Is there any automated way to assign each combination to a specific...
