friends, I am getting B error in columns named s9 and s11, I played with a reasonable amount of dimensions, I played with their smallness, I even increased the quality of concrete, and finally, I don't remember that the system to reduce the horizontal loads that can come to these columns was kackez, I even designed it all over again. I did everything that came to mind, it seems a bit cruel to me to use a column with a size larger than 30/70 in such a small project with an average of 2 floors of 100m2, so I hope my inexperienced friends can help me, where am I going wrong, also, the water column size in these columns on the floor ceiling and while I was able to save it from B with its smallness, I have this problem on the ceiling of the 1st floor. Since it gave the same error in the s5 and s7 columns, I adjusted the dimensions as 30/60. The whole system is requested to have a hollow floor, wet floors on the ground floor, low floor, all kinds of jokes and comments thank you.
