Shear shear force and relative storey drift

Hello. We have solved the high ductility of our project, which I added in the link, as it is ribbed in both directions (with 80cm-80cm cassette sizes), which is called cassette system, but we put 2 curtains due to the condition of the structure (R=7). However, we could not fix the following errors. We ask you to check if there is a place we missed. - We especially got the error of insufficient shear force on all floors of the p5 curtain (even if we enlarge its dimensions. We can't just change its direction). Columns close to the P5 curtain I mentioned above. -Although the relative floor offset exceeds the limit value only a little on the ground floor, we cannot save it. We also tried increasing the system rigidity. (Concrete class c30, increasing the column size, etc.) -And after a few analyzes, the raft basically gave a ground safety error. I would appreciate it if you could look into it and help with solutions. Thanks in advance. Download link;

Re: CURTAIN CUTTING FORCE AND RELATIVE FLOOR DIFFERENCE Hello, I have balanced your project. You basically have some negative momentum. Unver ÖZCAN
 
We were not able to recover the account somehow. Due to the decrease in ground values, we converted it to a rafter raft. In addition, we analyzed the system according to the fully rigid diaphragm, now when we convert it to semi-rigid; -We couldn't prevent the excess shear force on the curtains. We would be very happy if you could help us. Good luck with. The latest version is in the link below.

Enter the elevation of the KD13 low slab as -0.01 m on all floors. In the reinforcement selection dialog, select the stirrup diameter of 12 for the walls. The shear force problem on the curtains will be solved.

Too many reinforcements have come to the columns ( 35 /60 by 24 for example) how can we balance this by entering the way of increasing the size?

-In order to reduce the need for statically necessary pursantation in forced columns, it may be a solution to enlarge the column in the direction it is forced. Examining and evaluating the entire carrier system as a whole may lead to more economical solutions. Note: - There is a relative floor offset problem in the y direction in the project. It is appropriate to increase the system rigidity in the Y direction. (The long side dimensions of the columns on the 1 axis can be arranged in the y-axis direction and the column dimensions can be enlarged.) -For the lack of stirrups in continuous foundations, double stirrups can be used and the diameter of the stirrup can be increased. Good work
