Q$2$:

For a $6\mathrm{.}0m$ span fixed beam both ends

Where fixed end moment $=P\frac{L}{8}$ and mid$-$span moment $=P\frac{L}{8}$

It is loaded by a concentrated load $Pu=30kn$ as shown

Find top steel for $-$ve moment and bottom steel for $+$ve moment

Design for shear and torsion

$F^{\text{'}}C=25$Mpa

$Fy=420Mps$

$Fyv=Fyt=250$Mpa

Beam dimentions $(350350)mm$

Cover to steel center $=50mm$

Use $20mm$ steel and $10mm$ steel for torsion and shear stirrups
