For the column sections shown below, construct the moment curvature diagrams about the $x$ and $Y$ axes. Then briefly discuss your results and compare the performance of the two columns about the $x$ axis and $Y$ axis.

Distance from face of concrete to nearest bar is $65mm$

$f_c^{\text{'}}=32$MPa

Grade $420$MPa steel

$e=50cm$
