Design approach:
The column is designed using the following procedure:
(1) The column design charts are constructed.
(2) The design axis and design ultimate moment is determined .
(3) The steel required for the design axial force and moment is read from the
relevant design chart.
(4) The area steel perpendicular to the design axis is read from the relevant
design chart.
End fixity and bracing for bending about the Y-Y axis:
