Greetings, Change your concrete class to C30. Do not use C20 concrete as much as possible, to avoid the issues mentioned in both element sizing and the structure error shared in this forum. Place a panel on the right side of the elevator bucket instead of the K11 beam, and the stud beam here will disappear. Also, on the 3rd floor, you have a console above the console, why did you do this, can't you come out as the only console? I think you can't change the column dimensions as direction because I don't see the architecture. Just play with their dimensions and increase their short magnification enough to reduce the B problem. place the ladder and solve it semi-rigid I think. Also, do not make a console on a console, solve it as a single console, you will relax the system.
