I can't get past the deflection control

I am a new user of İdecad Çelik program. I am working on the project that I have attached. I cannot fix the deflection problem in the project and the sections are too much. I'm checking the project and waiting for your suggestions. (The base was deleted because the project size exceeded the limit)
 
Hello there; As you can see in the attached picture, your analysis model is set up incorrectly, and the steel columns do not move with the building since they do not coincide with the reinforced concrete columns or beams on a lower floor. To resolve this situation; 1- Define additional beams that will pass under your steel columns, or 2- Shift your steel columns to coincide with existing columns and beams, or 3- Dissolve the steel floor independent of the reinforced concrete building (not recommended) Regards.
 
Hello, I suggest you to put the steel columns on the reinforced concrete columns of the lower floor. Unver ÖZCAN
 
Hello there; In your model, steel columns are placed on reinforced concrete slabs, the program does not transfer loads from steel columns onto slabs. It is not healthy to install the carrier system in this way, remodel your steel columns so that they correspond to reinforced concrete beams and reinforced concrete columns. The carrier system seems to be easily revised in this way. After the analysis, you do not see any insufficient personnel. When the PMM ratios and deflection values are examined, it is seen that you have the opportunity to reduce the section. After arranging the carrier system, check your sections again.
