Friends, I'm going to solve a 104 m2 slab as a mushroom right now, my column spacing is not very much, I have 10 columns in this m2, there is no problem with that, but I made the solution by taking half r, j, td, yafram and I connected the columns with beams in the thickness of the column and 25 slabs and I did not encounter any errors when I did the solution by defining the beam height. I did not understand why there were no errors in the 25 cm high beams on the floor between 2 columns with only 6 m span or the column header was not removed. I didn't know. Thanks in advance to those who gave CVs....
