Question $(2)$

A $150mm$ thick concrete slab is reinforced with $15M$ bars at $300mm$ spacing $(15$M@$300).$ The

concrete cover is $30mm.$ the concrete and steel material properties are given below.

A$-$ Find the factored moment resistance per metre width of the slab.

B$-$ If the slab is simply supported in one direction over $5m$ span, find the safe specified live load

this slab can carry in addition to its self$-$weight. Refer to NBC $2020$ for the load combinations.

Given:

$f_c^{\text{'}}=30$MPa

$f_y=400$MPa

${}_c=0\mathrm{.}65$

${}_s=0\mathrm{.}85$

${}_w=24k\frac{N}{m^3}$
