QUESTION $1[25$ MARKS$]$

An R$.$C beam of dimensions $600$ x $300$ mm simply supported rectangular beam spans $8\mathrm{.}0$ m to the centre of supports.

The beam carries its self$-$weight and live load of $30$ kN$/$m$.$

Use the following information:

$$ fcu $=25$ MPa,

$$ fy$=450$ MPa

$$ Concrete cover $=25$ mm

$25$ for tension, $16$ for compression and $10$ bars for shear reinforcement.

$$ Assume the deflection is acceptable $($ no need to check$)$

$($a$)$ Calculate the ultimate design moment of the beam. $(7$ marks$)$

$($b$)$ Provide the suitable tension and compression reinforcement$($s$)$ for the beam. Check all necessary code requirements. $(18$ marks$)$
