In addition to what Unver said; * On the 1st floor, S3, S34 column pierces the floor, it is not connected to any beam. * You made ribbed flooring on this floor (1st floor), even on this floor, you did not connect the B and O axes mentioned by Ünver Bey with beams. * Your curtains stand idle. It does not contribute to the system, the curtain P1 is only connected in the Y direction. P2 curtain is only connected to other curtains. * On the 1st floor, the 25/50 beams on the right and left of the P1 curtain are connected to the lower 50/30 beams. Definitely fix it. * Divide the K1 and K25 beams into three parts (four on the other train), whereas I recommend combining beams K31-32 with 63-64. There are issues like this on other floors as well. (such as beams in front of the stairs, K74-75, etc.) * If you have the opportunity to place columns on the right and left of the stairs, you can connect the beam with the curtain. * Unver asked, "Is there a wall load on each beam?" If there is no wall on each beam, it sounds like there may be walls on the floor, check your loads. * At least, since there are consoles at the top and bottom, it would be good to have amps on those fronts, basically. * Since your floor live loads on all floors are 0.2, I would like to remind you that making the floors too thick is not a plus, but also a negative in terms of the mass of the building. I wish you good work. N. YILMAZ
