Hello My suggestions; --one. your basement floor is not rigid, correct it in the floor general settings, --You chose the R coefficient of 8, the program gives a warning after the calculation, 7 should be selected, --The building is semi-rigid diaphragm, solve it together with the stairs, --why did you make the ND03 flooring in front of the stairs, there is no transition, it can be removed, --There is a wall load on the beams in the attic, --Foundation beams overlap on the A axis and there is a floor edge, --If I were you, I would make a solution without putting beams on the sides, when you solve it like this, the floor safety on the foundation with S20-21-23 columns is a bit too much. If you cantilever on the raft foundation in front of the G axis, the ground safety can be saved. If you can do it in the same way, it would be better if you enlarge the raft foundation by 50 cm from the other 3 sides. --Stud beams are too much, --I suggest you to put flooring for the elevator machine. Good luck with. Unver ÖZCAN
