I not only need the steps to solve the problem, but also the solution for better understanding the steps. Because I need to find the numerical results as well, thanks for your help!

Task: Design the flat reinforced concrete beam T$304,$ with respect to the ultimate limit state requirements $($bending moment and shear force$)$ and sketch the reinforcement layout.

Data:

Concrete class C$28/35$

Steel class: B$450$C

Section of $t^{\text{'}}\text{'}$

CONC

Equivalent load of internal partitions $=1\mathrm{.}0k\frac{N}{m^2}$

Intended use: school building $q=3\mathrm{.}0k\frac{N}{m^2}$

$N$ equal to $22$ in $[$cm$]$ M equal to $22$ in $cm$
