Hello My suggestions; --Your building says HOUSING, but as far as I understand, you have taken the importance factor of a school or dormitory as 1.4. --Your building is very heavy, if you are going to make a floor without beams, a model like yours was made a long time ago. If you do these, don't forget to check the stapling, --If you can put the curtains gathered on one side, add curtains to balance them, --It would be nice if you could put beams on the adjacent exterior of the building, --Increase the floor safety by 50% as the floor is group B, --Move you can get the load of 0.35 t/m2, --take the load-bearing system coefficient of 7, --support the ladder and solve it together, --reduce the live loads on the attic floor, remove the wall loads, --if you don't make changes in the project, correct the errors in the geometry control. If there is a problem after doing these, we will look again Ünver ÖZCAN
