Office building suggestions..

The attached project is an office project. The ground floor height is 5.50 m. However, the 2.75 height passes through the stairwell and the frame beams. This is what's on my mind. Should I consider this floor as single or 2 floors? So, should I take the floor height to 2.75 and make it 2 floors, or should I take 5.50 and make it a single floor? Waiting for your suggestions. Thanks in advance.
 
If there will be objects that will provide rigidity at 2.75 elevation, my personal opinion is that they should be considered as 2 separate floors, or the system should be entered as 2 floors and the floor should not be defined and the program should not recognize a rigid diaphragm.
 
Dear aozhan90 My suggestions. 1- Building modeling is correct, 2- Stair bracing must be corrected, (bucket space is supported, etc.) 3- I could not understand why such a flooring solution was made on the top floor. Beams can be placed at the D1 and D2 floor joint. 4- In the same way, beams can be placed in the ground floor D4 slab space. If you say you can't, lay the floor between TU, AA-X, put the ladder on this floor, 5- Check the wall loads, 6- Check the (B) errors in the columns, 7- Fix the errors in the geometry control, Take it easy Unver ÖZCAN
 
I think this model is correct because there is no flooring. One point that draws my attention is the 1st period of the structure is 0.73, but when I look at the deformations from the 3d frame, there is no error in my interpretation?
 
Greetings, In addition to friends, the stair support on the ground floor is not complete. In the 4th mode, the stair landing dances separately :roll: Also, the period seems too high for a 4-storey building. as if it could be a little more rigid :hmm
 
Since there is no diaphragm in the section where the frame beams are, it should be modeled as a single floor. Floor means diaphragm in floor plane.

Proisa made a right point. Any other modeling would be wrong. Good work.. .
