For Column A located on level $1,$ consider a design compressive force $N^{*}$ of $96kN$ and a design bending moment $M^{*}x$ of $20$ kNm about the centroidal axis of Column A$\text{'}$s cross$-$section, which is parallel to the major axis of the building.

The column contains $2\%$ longitudinal reinforcement and a cover thickness of $50$ mm$.$

For tension failure, $ku=0\mathrm{.}45.$

The Concrete Mix Design is $32$MPa.

The steel bars to be used are $500$ N $.$

Assuming that Column A is a braced column, construct the interaction diagram and determine whether the column is safe under the given combined loading.
