Hello. My suggestions -- Curtain concretes C35, others C30 (column, beam, slab) --Curtain concrete C30 is seen in the curtain details. --It is very difficult to adjust different concretes while pouring the formwork concrete. For this, make the concrete the same everywhere. --When calculating, remove the DS check of the columns, --Additional reinforcements are jammed in the beams, choose the additional irons thicker, if there is any jamming, put them in the second row, --Curtain cap irons may be 16. --Increase the balcony live loads, --If there are no walls in the attic, remove the wall loads, you can reduce the live loads on the eaves, --The ends of the long curtains in the middle (P1-P4) are not connected in the long direction, (you can make the k47-k49, k54-k56 beams as curtains) - - Won't the elevator tower be built? --Add the ladder loads. Good luck with. Unver ÖZCAN
