Hi, i'm trying to model a column that runs from the ground floor up to the 2nd floor without connecting to the 1st floor slab, that is length as one column should be double that of the other column and therfore its effective length is consequently larger than other coulmn. But, it seems to me that ETABS doesn't allow one column to run up 2 stories without breaking them up into two columns at syory levels. Can anyone help me with this?
