Hello, There does not appear to be a problem with superstructure information entry in your project. However, since there are no perimeter curtains on the basement floor, it would be appropriate to enter -Upper rigid basement floor number- as -2 in the Analysis Settings/TDY Options Tab. Basically, the console mat tile you created has no function. Here, either place a raft slab in the area limited by the foundations of TK3-TK6-TK11-TK14 (in this case you can remove the amplifications of the TK11 and TK6) or not at all. It would be appropriate to define the TK14 continuous foundation from the bottom and place it in such a way that it covers the entire S9 column. Good work
