As we are designing using code IS13920:2016, The program shows error column design
“ *** ERROR: MINIMUM DIMENSION OF COLUMN # 7153 SHOULD NOT BE LESS THAN (a) 20 TIMES THE DIAMETER OF THE LARGEST LONGITUDINAL REINFORCEMENTZ(b) BAR OF THE BEAM AT THE COLUMN JOINT AS PER CL 7.1.1 a) OF IS-13920:2016.”
While the column size I am providing is 320 mm (Minimum) which shall satisfy this clause as I have restricted the bar diameter in beam and column to 16mm. So 20*16 = 320 mm
Moreover I even checked changing column size to 400 mm (Minimum) Still this error is not gone. Kindly find attached input file for reference.

In your model, you have placed Design Beam command after Design column command. But to check the criteria of minimum dimension, the program needs beam design results before it starts column design. So, place the beam design command ahead of column design and your issue will be solved.
