Problem III $($Verv important$)$

The floor system used in a school classroom consists of a $1120mm$ thick

reinforced concrete slab.

Given:

$SDL=1\mathrm{.}6k\frac{N}{m^2}$

$LL=3\mathrm{.}2k\frac{N}{m^2}$

Concrete specific weight is $25k\frac{N}{m^3}$

a$-$ Sketch and calculate the loading that acts along the beam $DF$ and

edge beam $AM.$

b$-$ Sketch and calculate the loading that acts along the side girder

ABCDE.

Note: beam$-$girder and girder$-$column are treated as pinned connections
