Problem $2$: $(30$ Points$)$

For the floor framing shown below, select the most economical HE A$/$B$-$shape for members B$1$ and

G$1.$ The floor dead load is $3\mathrm{.}6k\frac{N}{m^2}($including the weight of the framing$)$ and the live load is $3\mathrm{.}8$

$k\frac{N}{m^2}.$ Use S$355$ grade steel. Check bending, shear, and deflection. Assume that B$1$ has full lateral

stability and G$1$ is braced at the beam joints.

$F_y=235$

$F_4=$
