Question NO$.1$:

The shown beam is carrying dead load $40K\frac{n}{m}$ and Live load $30K\frac{n}{m},$ assuming the cross section is rectangular and concrete of grade C$30$ and steel S$460$ for main RFT and $250$ for transverse RFT$.$

$(1)$ Draw bending moment and shearing force diagram.

$(2)$ Design critical sections for shear and moment.

$(3)$ Draw cross section detail with scale $1$:$10.$

$(4)$ Draw longitudinal section detail with scale $1$:$25.$
