Hello!
I designed a foundation slab with thickening around the perimeter.
I made the slab as two slabs of different thickness. How can two boards of different thicknesses be joined? If you go through the <Panel> option, only one thickness panel can be used there, and when connecting the slab, one thickness is defined.
Maybe there is another way to connect two foundation slabs of different thicknesses?
Thanks!
Did you create the 2 thickness before using panel option?

Select panels one by one

Thanks for the reply. But I still don't understand how you can select one by one. Because when selecting both panels, only one thickness can be defined... either TH30 or TH70. Then either one TH30 panel or one TH70 panel is formed when connected. Honestly, I don't understand why it's so difficult.
Don't select both panels at once
Select panel 1216 and apply it thickness 1, then select panel 1258 with thickness 2

Thanks for the reply. but it already does not connect panel Thickness 1 with panel Thickness 2 into a common single panel. They are still two separate panels, one with Thickness 1 properties, the other with Thickness 2 properties.
I also tried the option when the TH30 panel covers the TH70 panel.
But then the program throws the warning <overlapped panels>. Does it affect the calculation result?
You have geometric discrepancy in your panels.
Could you zip your model and share it

That's the wat it is. In your case ,you will never have a single panel with 2 different constant thicknesses.
But the 2 panels are connected anyway.
If the 2 panels are 2 concentric squares , just create the larger one with its thickness and then create the smaller one "over" it. RSA will understand and there will be no overlapped panels warning

Hello. Thanks for the reply. <create the larger one with its thickness and then create the smaller one "over" it> means that if the upper panel is 300mm thick and the lower one is 400mm, then I place the lower panel 350mm lower than the upper one. See picture. I understand correctly?
No
Create first the external contour with 70 cm thickness, then the internal contour with 30cm thickness, you'll get something like the picture below
If you want to have the upper faces at the same level you may move down 20 cm the external panel using rigid links

Hello. Thanks for the reply. Creating two panels like this will connect them (shown in red in the picture)?
I'm confused by the deflections, they're easier to control 🙂 After calculation, looking at <Results-maps>, panel deflections are like one common panel.
But when calculating <Slab-required reinforcement> and <Slab-provided reinforcement>, panel deflections are divided for each panel separately. And the reinforcement for each panel is also separated.
This is a bit worrying.. The question is whether when calculating in the <Slab-required (provided) reinforcement> section, each panel is calculated separately, not both together?

Yes
...panel deflections are like one common panel.
No.
It's one slab made of 2 panels. Why did you expect different deflection at the common edges?

The reinforcement is calculated for each panel according to its thickness and its internal forces.

Hello. I have another question. When calculating the coefficient K of the soil, the dimensions A and B must be specified for the slab. The real dimensions of the slab must be specified, for example A=70m, but B=32m? Or are there any restrictions, for example, the area cannot be larger than 10x10m.
