Column orientation plays major role in design of structures. Irrespective orentation of column leads to increase in c/s of column to withstand the moment occured, which can leads to increase in project cost. Orientation of column is fixed using the Bending moment. Generally if Moment across X direction is higher then Long face of column should be oriented along X direction. In simple words. if length of span is 25ftx10ft longer face of column should be placed along longer direction to restrain moment created by long span of beam.
