Problem $3$

Design a rectangular section for a simply supported beam of span length $=5m.$ The beam is to support a dead load of $10k\frac{N}{m}$ and a live load of $15k\frac{N}{m}.$

Use $f_c^{\text{'}}=28$MPa and $f_y=420$MPa. Use only $\frac{O}{25}$ for main bars and $\frac{O}{10}$ for stirrups.

Determine the appropriate section dimensions $($width and height$)$

Choose the needed bars to satisfy the requirements of steel reinforcement

Determine the shear and flexural capacities of the chosen section

Draw the details of the final section

Hint,... Start with $b=200mm$ and $d=500mm$
