It is a situation that there may be more reinforcement on the upper floors compared to the lower floors. However, if you add your project to the message, we can see if there is a problem as a data entry. ."design":nfln9a9f" said:I couldn't find a solution to this problem. I enlarged the diameters of the reinforcements and the column size did not work. I didn't. I got 20 pieces of 16-gauge iron on 3 floors for the fretted column with a radius of 35; 40 pieces of 16-inch iron on the 4th last floor. come on If there is more than 4, 5 irons, I will make all the floors the same, but it will be a bit of a problem if there is 20 difference.
