Hello. You should get the upper rigid basement number -3 instead of -1 because it's -1 and -2. It does not create a rigid basement in its basements. Also, you have taken all beam loads of 0,800 tf/m, which increases the residual strength of the system, but makes the results uneconomical. In addition, the console dimensions of the raft foundation have become large. Finally, when I looked at a symmetrical half of the system, I saw 10-13 studs. Although it is easy to say something without looking at the architectural project, it still seemed too much for me. Good work everyone...
