Hello, In the project you added, the analysis is completed on our computer. The findings and suggestions for data entry in the project are generally as follows; -You can choose the ductility level High and get the Structural system behavior coefficients of 7. -Check the superstructure interactive solution option in the analysis settings. -I suggest that the elevator shaft be modeled without leveling the curtains and the raft foundation should be modeled as flat, and the elevator pit detail should be given separately. - Model the P04-P05 panels as one piece with the same thickness and the same name. You can enter P02 and P03 panels as columns. -5. The elevation of the D10 tile on the floor is not compatible with the P01 and P06 panel. If there is no problem in terms of architecture, it would be appropriate to define P01 and P06 along the floor height. (Or you can define the floor edge parallel to the curtains, 1-2 cm inside the curtains so that it does not connect to the curtains.) Good work.
