Question $4)(20$marks$)$ The cross$-$section of a continuous one$-$way solid slab in a

building is shown below. The slabs are supported by beams that span $4m$ between

simple supports and the width of beam $=30cm.$ The dead load on the slabs without

self$-$weight is $4K\frac{N}{m^2}$; the live load is $5K\frac{N}{m^2}.$ Given: The concrete strength is

$f_c^{\text{'}}=24$MPa, and the yield strength of the stirrups is $f_y=420$MPa.

Find:

$1-$ Determine the total slab and beam thickness $.(10$ marks$)$

$2-$ The moment in the solid slab from $($C$,$D$,$E$)$ sections that shown in the section

below and the ultimate shear force that the solid slab must be designed to carry

it$.(10$ marks$)$
