$AB$ column is a steel$-$concrete composite column and it's cross section is given with Figure $1.$ Loads on the beams are given with $q_1(k\frac{N}{m})$ and $q_2(k\frac{N}{m})$ and lengths of the beams are given with $L_1(m)$ and $L_2(m),$ respectively. All of the beams are pin supported and $AB$ column is fixed supported from point $A.$ If the area of the steel profile is $A_{\text{p}\text{r}\text{o}\text{f}\text{i}\text{c}}(m{m}^2)$ and the diameter of each rebar is $\frac{O}{?}($mm$),$ Elastic modulus of concrete is $E_{\text{c}\text{a}\text{s}\text{c}\text{u}\text{s}}$ and the column dimensions are $c(mm)xc(mm)$ determine the normal stress in concrete, steel profile and rebars.

Note: Elastic modulus of steel profile and steel rebars are the same as $E_{\text{t}\text{e}\text{c}\text{e}\text{l}}=200$GPa.

There are $8$ rebar on the section.
