Mr. Levent; Thank you for your interest, I corrected my mistake. I shared the jpg screenshot below.. 1st case. The value of 50 cm, that is, what parameters determine this value. Is it related to the raft depth; normally the number of floors*10 = the raft depth... 2nd case. axis of calculation..for example here, in cases where there is no proper geometry, what kind of way should we not follow in order to prevent the reinforcement from appearing in too many quantities..we can find out by trial method, but I am waiting for your advice on this subject...with my respects.. . . . . . . . . . . . . . . . .
