Turkish Hello. In a project, the ground floor will be used as a shop and a basement floor. There are 11 floors on approximately 800 m2. Their living area is approximately 400 m2. In such a project, can we solve the living area of the apartments as a raft and the parts of the shop as a continuous basis? Logic In terms of engineering.
both raft and solid foundation

The definition you will make in this way will be against the data entry rules for the program version 7. To explain in general: In the program, raft with and without beams It is possible to define raft in two ways. In beamed raft, continuous foundations should be connected to the columns in the form of a grid, and between continuous foundations, raft slab should be defined. In non-beamed raft, raft boundary should be defined with the slab edge and raft slab should be defined inside the slab edge. Beamed raft, beamless raft systems they can be found in the same project, but -as in the question you asked-- they should not be massively connected with each other (connections can be made in versions 8 and higher, valid for version 7.)"wind20":9gbybfol" said:
For your first question, There is no harm in making some part of it as a raft and some of it as a permanent basis."wind20":9gbybfol" said:

Mr. wind20 I think you are not talking about different elevations, one side of the foundation that you will build at the same level will be a raft and the other side will be continuous.
Sir, I take the foundation depth into account on the raft basis. I know the ground=Qtotal/area -df*y raft foundation formula as df foundation depth(distance from 0 level to the foundation base) I first analyzed according to one basement, then I changed the elevation or I made 2 basements too much. There was no change because of the ground tension, or I know my formula is wrong, how does the program calculate it?

Hello, In the program, the stress calculation on a beamless raft foundation is; multiplied by the coefficient."matrax":1kfvu57n" said:
Thank you very much for the information you have provided. However, I am stuck at this point. Do I need to connect all the columns and curtains with the foundation, basically? In my project, the elevator area is troublesome. I can't leave the elevator shaft because of the ampatmans when the building is built as a foundation. Is it wrong to surround the part of the building with a continuous foundation and define it as a raft? I'm waiting for your help on this 
I'm adding my project.

As far as I understand from the perspective, the number of floors in the building is too much, why don't you just solve the raft as a basis. The system is both comfortable and you
the building is ground+12 floors. It is a bit difficult to use the entire raft in terms of cost. Therefore, I want to use it on a regular basis. I want to add my project, but it cannot be loaded. Do you think it would be better to solve the entire raft in such a structure or using the built-in foundation as well. Thanks in advance. .
I have one more question. I make the whole raft foundation and solve the superstructure without interaction. In this case, when I examine the report results, the moments on the raft are 0. Does this mean that the system is in full balance or is there a problem? I await your urgent help.

Add to your project where the raft laying moments are zero, let's examine it.There is an error in the data entry."wind20":121bux4t" said:
