d)1225mm2

Answer 2

The rectangular beam of width, 350 mm is having overall depth of 600 mm. The

concrete grade is M30 and the grade of reinforcing steel is Fe415. The tensile

reinforcement is provided by 3-20 mm dia bars. The provided area of steel is equal

• The  concrete grade is M30
• the grade of reinforcing steel is Fe415

• The tensile  reinforcement is provided by 3-20 mm dia bars

calculate the  provided area of steel is equal

$\text { Area of tensile reinforcement, } A_{s} \text { t }$

$=n_{t} \pi \phi_{t}^{2} / 4$

$= 3\times 3.14159 \times 20^{2} / 4$

= 942.4777 m$m^{2}$
