I had a chance to review it for a very short time. Hollow hollow structures are usually made with an architectural design focus, so the purpose is to hide the view of the beams. In other words, instead of making a stud beam on the wall, beams can be connected to the columns even if they are diagonally. Of course, wall loads should be defined as distributed loads in the relevant places. Since your curtains in the basement are only underground curtains, I suggest you define "flood curtains that do not continue on every floor". Also, it may be better to use 25/32 perimeter beams to connect the hollow blocks on the balconies. In some places, as far as I can see from the architecture, the walls are outside and you have to make the necessary offset adjustments so that they fit on the beams. When this is the case, it is seen that the 25/60 beam is insufficient. You can make a hollow beam there, too. Pay attention to your typical beam definitions. where the span is between 4-7 m, it may be sufficient to arrange 1 transverse tooth. I wish you the best of luck with what you can see. Best regards.
