Problem $4$

a$.)$ Design the floor one$-$way slab shown below. Draw detailing of steel reinforcement on the plans

b$.)$ Design rectangular sections for the beams on gridlines $E$ and $D.$ Show sketches of cross sections including bar sizes, arrangements, and spacing.

Knowing that:

$f_c^{\text{'}}=28$MPa

$f_y=420$MPa

$$ Beam section $250500mm$

$$ Girder section $250700mm$

$$ Column section $250350mm.$

$$ Superimposed dead load SDL $=2\mathrm{.}5k\frac{N}{m^2}$

$$ Live load $LL=2\mathrm{.}4k\frac{N}{m^2}$

$$ External beams$/$girders support a wall load $w_{\text{w}\text{a}\text{l}\text{l}}=4k\frac{N}{m}$
