Hello My Suggestions --Fix the errors in the geometry control, --If you are going to dilate on the raft foundation, do it on the superstructure as well (You worshiped the opposite of the general practice. The superstructure dilated foundation is made as a whole.) --If you are not going to do it, dissolve the raft foundation without dilatation, (give a single thickness 90 cm) - -Increase the thickness of the raft foundation reinforcement, -You can remove the negative control on the raft foundation, -Increase the stiffness of the basement in the x direction since there is no curtain on one side of the building, -Take the ladder loads -Check the wall loads -The thickness of the curtains in the basement floor should be increased [b ]When I have the analysis done by changing the following:[/b] --I did the foundation without dilatation, --There is a problem in the additional reinforcement, as you did not give the P22-P23-P24 curtain separately. I put a colon between P23-P24, no problem. (There are errors in other tiles, they should be fixed) Take it easy Ünver ÖZCAN Corrected project:
