Dear hatice.mert * Do not make such large gaps with the slab gap command. (3rd floor stairway, ground floor stairway) * Why did you break the continuity on the normal floors in the building? Is it that important to break the ties of columns s6-s8 and s12-s16? * The direction of all columns without exception is in the Y direction. You should arrange the columns as staggered as possible. * Moreover, in the console part, the column is not connected in the x direction. p4, p19 * You have made cantilever beams from the s3 column on the mezzanine floor. Dear Mert, There can be much more to be said about this project. I think you should rework it and give it a good overhaul. It seems very normal for the alpha to appear this way under these conditions. You can clear some of your doubts by talking to the architect. Maybe it can allow for the beams you're afraid to do. Overhaul the column placement. Try to make columns in the X direction, but return to square columns. Pay attention to the continuities. Console balconies in this opening deflect. I advise you to take precautions. I think that's enough for now. Good work. N. YILMAZ
