How to determine the direction of stiffness

hello, I need the information of my experienced friends. Since B2 has curtains on 3 sides, I assumed rigid in both directions. Since B1 has long curtains in Y direction, I assumed rigid in Y direction Are my stiffness direction determinations in the project correct? B2 which is not in B1 I marked the curtains in the basement as "curtain that does not continue in the upper floors". I also marked the curtains in B2, which is not on the ground, as "the curtain that does not continue in the basement / upper floors". Are these applications correct? if not what should i do? In the structure summary information, it gives the shear problem in the P021 curtain in Z, the shear problem in the S019 column in B2, and the error that double reinforcement is required in 4 slabs, how do you suggest I solve them? Best regards...

There is no clear explanation regarding the acceptance of rigid basements in the current regulation. Sometimes rigid acceptance can be made when three sides are closed with curtains. But to me, the open façade in your project is one of the long façades. In addition, the facade in question is quite indented. I think that these issues should also be taken into account in rigid acceptance. Your admission on the 1st basement floor was already wrong. If you are going to make a stiffness definition there, you should do it in the x direction, not in the y direction. But for the x direction, as I wrote above, the other side is open. Curtain p002 in the 1st basement does not continue on the floors, it can be marked. The description of P020 is correct. S30 col
