Basement fill calculation

Have a nice day; In the project I took, there will be 130 cm high curtains under the basement at -2.60, and there is a 30 cm raft under it. A 130 cm high soil fill plus blockade will be made under the basement. Are the data correct for such a system? Is there an error? Also, for the low floor I made for the engine room on the 3rd floor, when I solve it with more than one diaphragm, the 3rd floor gives a relative translation error, if I solve it with a single diaphragm, it does not give an error? How can we fix the relative offset if the first solution has to?

Hello, My suggestions about the formwork plan, I recommend you to use beams in the places I indicated in red, and to define curtains around the elevator. It would be appropriate to continue the S108 column to the upper floor with a longer console distance on the tower floor. Since the engine room floor is a small floor, it can be solved with the option of creating a rigid diaphragm in this floor and it can be preferred to ignore the relative floor drift control. For this, the engine room floor (D14) can be selected and the option "Creating a rigid diaphragm" can be selected.
 
I will consider the warnings, thanks, but is there anything else to be done for the filling calculation under the basement? Is this solution suitable?
 
You can enter the load that will come from the soil fill + floor concrete on the raft foundation as the coating load. In addition, you must enter the live load on the raft flooring according to the purpose of use. Considering that there is 115 cm of earth fill and 15 cm of slab, 1.15 x 1.8 = 2.070 0.15 x 2.5 = 0.375 Total = 2.445 t/m2 pavement load. Recalculate according to the filling material you will use or the thickness of the flooring.
