A civil engineer designed a composite concrete column that is reinforced with $5$ steel rods having a diameter $\backslash (\backslash$mathrm$\{$d$\}=12\backslash$mathrm$\{$~mm$\}\backslash )$ as shown in Figure $1.$ The column has a height of $\backslash (\backslash$mathrm$\{$H$\}=3\mathrm{.}25\backslash$mathrm$\{$~m$\}\backslash )$ with a square cross$-$sectional sides of $\backslash ($ A$=450\backslash$mathrm$\{$~mm$\}\backslash ).$ The concrete column is fixed from the bottom while a compressive load $\backslash (\backslash$mathrm$\{$P$\}=550\backslash$mathrm$\{$kN$\}\backslash )$ is applied. Take the modulus of elasticity for the concrete and steel rods as $17$ GPa and $200$ GPa $,$ respectively. Determine:

$3\mathrm{.}1$ the maximum axial deformation of this composite concrete column, and

$3\mathrm{.}2$ the maximum stresses in the steel rod and concrete column.
