Dear members:I was wondering if anyone has gone through this before.ETABS 15, 16 & 18 are all giving me somewhat logical analysis values but wildly false design. Like failure due to buckling for a 20X60 3.2 meters high column in a typical villa. Or requiring a 17000 mm^2 for a column with only 650 KN axial load.It should be noted that this was not the case before.
